CR oscillator circuit equipped internally (external clock can also be input) Low power consumption. Logic power supply VDD – VSS = 2.7V to 5.5 V Boost reference voltage: VDD2 – VSS = 2.7V to 5.5V Booster maximum voltage limited VOUT=17.0V Liquid crystal drive power supply: V0 – VSS = 4.0V to 15.0 V Wide range of operating temperatures: –40 to 85°C CMOS process. Shipping forms include bare chip and COB. Software compatible to KS0108. GENERAL DESCRIPTION The RW1065 is a single-chip dot matrix LCD driver that can be connected directly to a microprocessor bus. 8-bit parallel display data sent from the microprocessor is stored in the internal display data RAM and the chip generates a LCD drive signal independent of the microprocessor. Because the chips in the RW1065 contain 64x64 bits of display data RAM and there is a 1-to-1 correspondence between the LCD panel pixels and the internal RAM bits, these chips enable displays with a high degree of freedom. The RW1065 chips contain 32 common output circuits and 64 segment output circuits, so that two RW1065 chips can drive a 64x128 dot display (capable of displaying 8 columnsx4 rows of a 16x16 dot kanji font). Moreover, the capacity of the display can be extended through the use of master/slave structures up to three RW1065 chips. The chips are able to minimize power consumption because no external operating clock is necessary for the display data RAM read/write operation. Furthermore, because each chip is equipped internally with a low-power LCD driver power supply, and a display clock CR oscillator circuit, the RW1065 can be used to create the lowest power display system with the fewest components for high-performance portable devices.

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

bullWhen V0 V1 V2 V3 and V4 are biased by external power supply analog section of RW1065 should be turn off by software during LCD initialization The example in below shows the sequence to turn off analog section when external bias is used Begin of LCD initialization 1 Reset RW1065 2 SET EXT=1 (mode instruction)

RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB00 0 0 0 0 0 1 1 0 1

3 SET Display Command (double command)

4 SET EXT=1 (mode instruction)

End of LCD initialization

bullBecause pins can not set LCD bias when external power supplies are used for LCD driving the bias can be set by an appropriate configuration for a resistor voltage divider networks The example is shown below

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

bullWhen V0 V1 V2 V3 and V4 are biased by external power supply analog section of RW1065 should be turn off by software during LCD initialization The example in below shows the sequence to turn off analog section when external bias is used Begin of LCD initialization 1 Reset RW1065 2 SET EXT=1 (mode instruction)

RS RW DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB00 0 0 0 0 0 1 1 0 1

3 SET Display Command (double command)

4 SET EXT=1 (mode instruction)

End of LCD initialization

bullBecause pins can not set LCD bias when external power supplies are used for LCD driving the bias can be set by an appropriate configuration for a resistor voltage divider networks The example is shown below

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

Figure 5

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

Table 5 shows the status of the FR and CL signals

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

DESCRIPTION OF FUNCTIONS

The Parallel Interface (6800 series MPU)

Shared 6800 Series

RS RW Function

1 1 Reads the display data

1 0 Writes the display data

0 1 Status read

0 0 Write control data (command)

The Chip Select The RW1065 Series chips have two chip select terminals CS1

―BP and CS2P

When the chip select is inactive D0 to D7 enter a high impedance state and the RS E and RW inputs are inactive

The Accessing the Display Data RAM and the Internal Registers Data transfer at a higher speed is ensured since the MPU is required to satisfy the cycle time (tCYC) requirement alone in accessing the RW1065 Series Wait time may not be considered And in the RW1065 Series chips each time data is sent from the MPU a type of pipeline process between LSIs is performed through the bus holder attached to the internal data bus Internal data bus For example when the MPU writes data to the display data RAM once the data is stored in the bus holder then it is written to the display data RAM before the next data write cycle Moreover when the MPU reads the display data RAM

the first data read cycle (dummy) stores the read data in the bus holder and then the data is read from the bus holder to the system bus at the next data read cycle There is a certain restriction in the read sequence of the display data RAM Please be advised that data of the specified address is not generated by the read instruction issued immediately after the address setup This data is generated in data read of the second time Thus a dummy read is required whenever the address setup or write cycle operation is conducted This relationship is shown in Figure 2

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

bullWhen V0 V1 V2 V3 and V4 are biased by external power supply analog section of RW1065 should be turn off by software during LCD initialization The example in below shows the sequence to turn off analog section when external bias is used Begin of LCD initialization 1 Reset RW1065 2 SET EXT=1 (mode instruction)

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

Figure 5

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

Table 5 shows the status of the FR and CL signals

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Display Data RAM The display data RAM is a RAM that stores the dot data for the display It has a 64 (8 page x 8 bit) x 64 bit structure It is possible to access the desired bit by specifying the page address and the column addressBecause as is shown in Figure 3 the D7 to D0 display data from the MPU corresponds to the liquid crystal display common direction there are few constraints at the time of display data transfer when multiple RW1065 series chips are used

thus and display structures can be created easily and with a high degree of freedom Moreover reading from and writing to the display RAM from the MPU side is performed through the IO buffer which is an independent operation from signal reading for the liquid crystal driver Consequently even if the display data RAM is accessed asynchronously during liquid crystal display it will not cause adverse effects on the display (such as flickering)

The Page Address Circuit As shown in Figure 4 page address of the display data RAM is specified through the Page Address Set Command The page address must be specified again when changing pages to perform access

The Column Address As is shown in Table 4 the display data RAM column address is specified by the Column Address Set command The specified column address is incremented (+1) with each display data readwrite command This allows the MPU display data to be accessed continuously Moreover the increment of column addresses stops with 3FH Because the column address is independent of the page address when moving for example from page 0 column 3FH to page 1

column 00H it is necessary to respecify both the page address and the column address Furthermore as is shown in Table 4 the ADC command (segment driver direction select command) can be used to reverse the relationship between the display data RAM column address and the segment output Because of this the constraints on the IC layout when the LCD module is assembled can be minimized

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

Table 5 shows the status of the FR and CL signals

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

Figure 5

When multiple RW1065 Series chips are used the slave chip must be supplied the display timing signals(FR CL) from the master chip

Table 5 shows the status of the FR and CL signals

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Display Timing Generator Circuit

The display timing generator circuit generates the timing signal to the line address circuit and the display data latch circuit using the display clock The display data is latched into the display data latch circuit synchronized with the display clock and is output to the data driver output terminal Reading to the display data liquid crystal driver circuits is completely independent of accesses to the display data RAM by the MPU Consequently even if the display data

RAM is accessed asynchronously during liquid crystal display there is absolutely no adverse effect (such asflickering) on the display Moreover the display timing generator circuit generates the common timing and the liquid crystal alternating current signal (FR) from the display clock It generates a drive wave form using a 2 frame alternating current drive method as is shown in Figure 5 for the liquid crystal drive circuit

Two-frame alternating current drive waveform

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

The Liquid Crystal Driver Circuits

These are a 64-channel (RW1065) that generate four voltage levels for driving the liquid crystal The combination of the display data the COM scan signal and the FR signal

produces the liquid crystal drive voltage output Figure 6 shows examples of the SEG and COM output waveform

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

The Reset Circuit

When the RTP input comes to the ldquoLrdquo level these LSIs return to the default state Their default states are as follows 1 Display OFF 2 Display all point on is select to normal 3 Display normalreverse is select to normal 4 164 duty is selected 5 Read modify write OFF 6 Column address set to Address 0 7 Page address set to Page 0 8 Start line set to first line 9 Frame frequency set to default 10 Power save mode released 11 Ext set to ldquo0rdquo When the power is turned on the IC internal state becomes unstable and it is necessary to initialize it using the RSTP terminal After the initialization each input terminal should be controlled normally While RSTP is ldquoLrdquo the oscillator works but the display timing generator stops and the CL FR terminals are fixed to ldquoHrdquo The terminals D0 to D7 are not affected

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

The Power Supply Circuit

The power supply circuits are low-power consumption power supply circuits that generate the voltage levels required for the liquid crystal drivers They comprise Booster circuits and voltage follower circuits They are only enabled in master operation The power supply circuits can turn on automatically after power on

Consequently it is possible to make an external power supply and the internal power supply function somewhat in parallel

The Liquid Crystal Voltage Generator Circuit The V0 voltage is produced by a resistive voltage divider outside the IC through VRAB pin and can be produced at the V1 V2 V3 and V4 voltage levels required for liquid crystal driving Moreover when the voltage follower changes the impedance it provides V1 V2 V3 and V4 to the liquid crystal drive circuit 15 bias or 16 bias or 18 bias or 19 bias for RW1065 can be selected by BS0 and BS1 pins V0-Vss maximum voltage is 15V Vout-Vss maximum voltage is 17V If VDD lt 35V it can use the Booster circuit 2x3x4xThe booster voltage can follow the spec condition (Vout-Vss ≦ 17V max voltage) if VDD gt35V only use the 2X3X booster circuit that can ensure the V0-Vss voltage ≦ 15V If use the VDD voltage 5V and 4X booster itrsquos over the spec operation condition To turn on built-in power (boosterfollower) must waiting 200mS to display on for boosterfollower stable Therefore power off must follower ldquopower off sequencerdquo too

The Reset Circuit

When the RTP input comes to the ldquoLrdquo level these LSIs return to the default state Their default states are as follows 1 Display OFF 2 Display all point on is select to normal 3 Display normalreverse is select to normal 4 164 duty is selected 5 Read modify write OFF 6 Column address set to Address 0 7 Page address set to Page 0 8 Start line set to first line 9 Frame frequency set to default 10 Power save mode released 11 Ext set to ldquo0rdquo When the power is turned on the IC internal state becomes unstable and it is necessary to initialize it using the RSTP terminal After the initialization each input terminal should be controlled normally While RSTP is ldquoLrdquo the oscillator works but the display timing generator stops and the CL FR terminals are fixed to ldquoHrdquo The terminals D0 to D7 are not affected

Command Description

See the Table of RW1065 instructions The RW1065 series identifies a data bus using a combination of RS E and RW signals As the MPU translates a command in the internal timing only (independent from the external clock) its speed is very high The busy check is usually not required

Display ONOFF

0 0 0 0 0 1 1 1 1 1 D

This command turns the display on and off D=1 Display ON D=0 Display OFF(default)

Set page Address This command specifies the page address that corresponds to the low address of the display data RAM when it is accessed by the MPU Any bit of the display data RAM can be accessed when its page address and column address are specified The display status is not changed even when the page address is changed

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Command Description

See the Table of RW1065 instructions The RW1065 series identifies a data bus using a combination of RS E and RW signals As the MPU translates a command in the internal timing only (independent from the external clock) its speed is very high The busy check is usually not required

Display ONOFF

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 0 0 0 1 1 1 1 1 D

This command turns the display on and off D=1 Display ON D=0 Display OFF(default)

Set page Address This command specifies the page address that corresponds to the low address of the display data RAM when it is accessed by the MPU Any bit of the display data RAM can be accessed when its page address and column address are specified The display status is not changed even when the page address is changed

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

Write Display Data

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 1 0 Write data

Writes 8-bits of data into the display data RAM at a location specified by the contents of the column address and page address registers and then increments the column address register by one

Read Display Data

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 1 1 Read data

Reads 8-bits of data from the data IO latch updates the contents of the IO latch with display data from the display data RAM location specified by the contents of the column address and page address registers and then increments the column address register After loading a new address into the column address register one dummy read is required before valid data is obtained

Set initial display line register

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 0 1 1 S5 S4 S3 S2 S1 S0

Loads the RAM line address of the initial display line COM 0 into the initial display line register The RAM display data becomes the top line of the LCD screen It is followed by the higher number lines in ascending order corresponding to the duty cycle The screen can be scrolled using this command by incrementing the line address(default value=rdquo00Hrdquo)

Read-Modify-Write

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

1 0 0 0 0 0 0 1 0 0 0

This command defeats column address register auto-increment after data reads The current contents of the column Address register are saved The mode remains active until an End command is received When the End command is entered the column address is returned to the one used during input of Read-Modify-Write Command This function can reduce the load of MPU when data change is repeated as a specific display area Any command other than Data Read or Write can be used in the Read-Modify-Write mode However the Column Address Set command cannot be used

End

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Command Description

See the Table of RW1065 instructions The RW1065 series identifies a data bus using a combination of RS E and RW signals As the MPU translates a command in the internal timing only (independent from the external clock) its speed is very high The busy check is usually not required

Display ONOFF

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 0 0 0 1 1 1 1 1 D

This command turns the display on and off D=1 Display ON D=0 Display OFF(default)

Set page Address This command specifies the page address that corresponds to the low address of the display data RAM when it is accessed by the MPU Any bit of the display data RAM can be accessed when its page address and column address are specified The display status is not changed even when the page address is changed

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 0 1 0 1 1 1 A2 A1 A0

This command loads the page address register

Set Column Address This command specifies a column address of the display data RAM When the display data RAM is accessed by the MPU continuously the column address is incremented by I each time it is accessed from the set address Therefore the MPU can access to data continuously The column address stops to be incremented at address 63 and the page address is not changed continuously

Read Status

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 1 BUSY 0 ON OFF RESET 0 0 0 0

The BUSY Flag bit indicates that RW 1065 is operating or no operating

BUSY=1 Operation BUSY=0 Ready

The ONOFF bit indicates the current status of the display It is the inverse of the polarity of the display ONOFF command ONOFF=1 Display OFF ONOFF=0 Display ON The RESET bit indicates whether the driver is executing a hardware or software reset or if it is in normal operating mode RESET=1 Currently executing reset command RESET=0 Normal operation

Write Display Data

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 1 0 Write data

Writes 8-bits of data into the display data RAM at a location specified by the contents of the column address and page address registers and then increments the column address register by one

Read Display Data

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 1 1 Read data

Reads 8-bits of data from the data IO latch updates the contents of the IO latch with display data from the display data RAM location specified by the contents of the column address and page address registers and then increments the column address register After loading a new address into the column address register one dummy read is required before valid data is obtained

Set initial display line register

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

0 0 0 1 1 S5 S4 S3 S2 S1 S0

Loads the RAM line address of the initial display line COM 0 into the initial display line register The RAM display data becomes the top line of the LCD screen It is followed by the higher number lines in ascending order corresponding to the duty cycle The screen can be scrolled using this command by incrementing the line address(default value=rdquo00Hrdquo)

Read-Modify-Write

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

1 0 0 0 0 0 0 1 0 0 0

This command defeats column address register auto-increment after data reads The current contents of the column Address register are saved The mode remains active until an End command is received When the End command is entered the column address is returned to the one used during input of Read-Modify-Write Command This function can reduce the load of MPU when data change is repeated as a specific display area Any command other than Data Read or Write can be used in the Read-Modify-Write mode However the Column Address Set command cannot be used

End

EXT RS RW D7 D6 D5 D4 D3 D2 D1 D0

1 0 0 0 0 0 0 1 1 1 0

This command cancels read-modify-write mode and restores the contents of the column address register to their value prior to the receipt of the Read-Modify-Write command

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

bullWhen V0 V1 V2 V3 and V4 are biased by external power supply analog section of RW1065 should be turn off by software during LCD initialization The example in below shows the sequence to turn off analog section when external bias is used Begin of LCD initialization 1 Reset RW1065 2 SET EXT=1 (mode instruction)

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

End of LCD initialization

bullBecause pins can not set LCD bias when external power supplies are used for LCD driving the bias can be set by an appropriate configuration for a resistor voltage divider networks The example is shown below

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

When using external multi-level power supply for LCD driving (REFERENCE EXAMPLE)

Using a resistor divider can provide RW1065 external multi-level power supply for LCD driving

The circuit below shows a resistor divider network which can bias V0 V1 V2 V3 and V4 externally

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RW1065 64x32 Dot Matrix LCD Controller Driver

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

RockWorks Technology Corp

41

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

RockWorks Technology Corp

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

Package information (Please pay close attention to the information in this section Do not hesitate to consult with our sale representative if you have any question or concern)

In order to make better bonding yield for RW1065 please follow the tips and recommendations in this section In this section few tips about COB footprint style PCB layout and wire bonding will be discussed

The drawing in below shows the PCB footprint style which we recommend for RW1065 Pads array in

curve shape is easier for Al wire bonding Besides that a real size COB footprint for RW1065 is also shown in below RW1065 COB footprint is also available in powerpcb or protel format for design reference purpose

The ratio is 11

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

42

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding

During COB footprint design there have some tips about footprint that the PCB designer should know The angle between bonding wire and vertical line should less than 45 Otherwise the wire shorts would become very easy to happen at fours corners of the chip

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip In addition reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line The picture in below will help to illustrate this concept From the experiences COB footprint style affects the bonding yield

Bad Wires are too close to each other

The angle between bonding wire and vertical line is greater than 45

The angle between bonding wire and vertical line is less than 45

Wires are not too close to each other

Reducing length in horizon direction of pads array could minimize the angle between bonding wire and vertical line

The angle between bonding wire and vertical line could be reduced by expanding the distance between pads array and the chip

If the gap between pads of COB footprint is filled with solder mask coating it is difficult to bond Al wire to

the pads The top solder masks layer that overlap COB footprint area should be removed

Please use 1 mils diameter Al wire for RW1065 wire bonding
