Evaluation board with STM32G4xxQE MCU

Introduction

The STM32G474E-EVAL board is a complete demonstration and development platform for the STMicroelectronics Arm® Cortex®-M4 core-based STM32G474QET6U microcontroller. It features three FDCAN controllers, four I²C Fast mode plus, five USART/UARTs and one LPUART, four SPIs, one SAI port, USB FS and IRTIM communication interfaces, UCPD, five 12-bit ADCs, seven 12-bit DAC channels, seven comparators and six operational amplifiers, 17 timers, 96 Kbytes of internal SRAM, 32 Kbytes of CCM SRAM, 512 Kbytes of Flash memory, and JTAG/SWD debugging support.

The STM32G474E-EVAL, shown in Figure 1 and Figure 2, is used as a reference design for user application development before porting to the final product. The STM32G484E-EVAL is populated with an STM32G484QET6U MCU with Cryptography. The STM32G474E-EVAL1 is configured as a dedicated motor-control board.

The full range of hardware features available on the board helps users to optimize the application development by the evaluation of all the peripherals (USB FS, UCPD, USART, audio, ADC and DAC, differential ADC, TFT LCD, potentiometer/LDR, SRAM, Quad-SPI Flash memory device, microSD™ card, Smartcard, FDCAN transceiver, high brightness LED, motor control connectors, temperature sensor, and others). Extension headers provide easy connection to daughterboard for specific applications.

STLINK-V3E is integrated into the board, as the embedded in-circuit debugger and programmer for the STM32 MCU and the USB virtual COM port bridge.

The three products (STM32G474E-EVAL, STM32G484E-EVAL, STM32G474E-EVAL1) are described in this user manual, together with STM32G474E-EVAL figures.

5.1 STLINK-V3E

STLINK-V3E facility for debug and flashing of STM32G474QET6U is integrated on the STM32G474E-EVAL board. It features:

• Self-powered through a USB connector (Micro-B)

• USB 2.0 high-speed compatible interface

• Direct firmware update support (DFU)

• SWD and serial wire viewer (SWV) communication support

• Drag-and-drop Flash programming

• Two color LEDs: communication, power

The USB connector CN21 can be used to power the STM32G474E-EVAL regardless of the STLINK-V3E facility used for debugging or programming STM32G474QET6U. This holds also when the STLINK stand-alone tool is connected to connector CN14 or CN15 or CN16 or CN17 and used for debugging or programming the STM32G474QET6U. Section 5.3: Power supply provides more detail about powering the STM32G474E-EVAL.

Refer to www.st.com for details about STLINK-V3E.

5.1.1 Drivers and firmware upgrade

The STLINK-V3E requires drivers to be installed on Windows, and embeds a firmware which needs to be updated from time to time in order to benefit from new functionality or corrections. Refer to the Overview of ST-LINK derivatives technical note (TN1235) for details.

Before connecting the STM32G474E-EVAL to a Windows (7, 8 10) PC via USB, a driver for STLINK-V3E must be installed. It is available from www.st.com.

5.2 ETM trace

The connector CN17 is available to output trace signals used for debug. By default, the evaluation board is configured such that, STM32G474QET6U signals PE2, PE3 and PE4 are connected to trace outputs TRACECLK, TRACED0, and TRACED1 of CN17, but these signals shared with Audio codec, motor control connectors and FMC.

Table 3 shows the setting of configuration elements to shunt PE3 and PE4 MCU ports to CN17 connector, to use them as debug trace signals.

Table 4 shows the setting of configuration I/Os to shunt PE2, PE3, PE4 and PE5 MCU ports to use them as the right functions.

5.3 Power supply

The STM32G474E-EVAL board is designed to be powered from a 5 V DC power source. It incorporates a precise PTC and transil to protect the board from damage due to wrong power supply. One of the following five 5 V DC power inputs can be used, upon appropriate board configuration:

• Power jack CN25: Marked PSU on the board (JP12 jumper setting on E5V on silkscreen). The positive pole is on the center pin as illustrated in Figure 22. The External power supply from Power jack CN25 is from 5 V to 18 V input voltage. The dedicated DC/DC regulator ST1S41PHR is used for about 5.2 V output voltage and provided up to 3 A current.

• Micro-B USB receptacle CN21 of STLINK-V3E with enumeration: Up to 500 mA can be supplied to the board (JP12 jumper setting on STLK on silkscreen). Offers the enumeration feature described in Section 5.3.1.

• Micro-B USB receptacle CN21 of STLINK-V3E without enumeration: Up to 1000 mA can be supplied to the board directly without enumeration (JP12 jumper setting on CHGR on silkscreen).

• USB Type-C receptacle CN22 of USB PD interface: Marked TYPE-C on the board (JP12 jumper setting on U5V on silkscreen). Up to 500 mA can be supplied to the board in this way.

• Pin 49 of CN5 and Pin 49 of CN6 extension connectors for custom daughterboard: Marked 5V_D on the board (JP12 jumper setting on D5V on silkscreen).

The LD6 green LED turns on when the voltage on the power line marked as 5 V is present. All supply lines required for the operation of the components on the STM32G474E-EVAL are derived from that 5 V line.

Table 5: Power supply related jumper and solder bridge settings describes the settings of all jumpers related to powering the STM32G474E-EVAL and extension board. VDD_MCU is STM32G474QET6U digital supply voltage line. It can be connected to a fixed 3.3 V or with

5.3.1 Supplying the board through STLINK-V3E USB port

To power the STM32G474E-EVAL this way, the USB host (a PC) gets connected to the Micro-B USB receptacle of the STM32G474E-EVAL board via a USB cable. The connection event starts the USB enumeration procedure. In its initial phase, the host USB port current supply capability is limited to 100 mA. It is enough because only STLINK-V3E part of the STM32G474E-EVAL draws power at that time: the U25 STMPS2151 power switch is set to the OFF position, which isolates the rest of the STM32G474E-EVAL from the power source. In the next phase of the enumeration procedure, the host PC informs the STLINK-V3E facility of its capability to supply current up to 300 mA. If the answer is positive, the STLINK-V3E sets the U25 STMPS2151 switch to ON position to supply power to the rest of the STM32G474E-EVAL board. If the PC USB port is not capable of supplying current up to 300 mA, the CN25 power jack is available to supply the board.

If a short-circuit occurs on the board, the STMPS2151 power switch protects the USB port of the host PC against a current demand exceeding 500 mA. In such an event, the LD7 LED lights up.

The STM32G474E-EVAL board can also be supplied from a USB power source not supporting enumeration, such as a USB charger. In this particular case, jumper JP12 must be fitted with a jumper hat as shown in Table 5: Power supply related jumper and solder bridge settings. STLINK-V3E bypasses STMPS2151 power regardless of enumeration procedure result and passes the power unconditionally to the board.

The LD6 green LED turns on whenever the whole board is powered.

5.3.2 Using STLINK-V3E along with powering through CN25 power jack

When the board requires a current higher than 300 mA, the host PC, connected to STLINK-V3E USB port for debugging or programming, cannot supply the STM32G474QET6U MCU. In such a case, the board can be powered through CN25 (marked PSU on the board).

To do this, it is important to power the board before connecting it with the host PC, which requires the following sequence to be respected:

1. Set the jumper JP12 in E5V position

2. Connect the external power source to CN25

3. Check that the green LED LD6 is turned on

4. Connect host PC to USB connector CN21

Caution: In case the board requires more than 300 mA and the host PC is connected via USB before the board is powered from CN25, the following risk events are possible (listed in reverse severity order):

1. The host PC is capable of supplying 300 mA (the enumeration succeeds) but it features no over-current protection on its USB port. It is damaged due to over- current.

2. The host PC is capable of supplying 300 mA (the enumeration succeeds) and it has a built-in over-current protection on its USB port, limiting or shutting down the power out of its USB port when the excessive current demand from the STM32G474E-EVAL is detected. This causes an operating failure of the STM32G474E-EVAL.

3. The host PC is not capable of supplying 300 mA (the enumeration fails). The STLINK-V3E does not supply the rest of the STM32G474E-EVAL from its USB port VBUS line.

5.16.1 Operational amplifier

STM32G474QET6U provides on-board operational amplifier, OpAmp4, is made accessible on STM32G474E-EVAL. OpAmp4 has its inputs and its output routed to I/O ports PB11, PB10 and PB12, respectively.

The PB12 output of the operational amplifier can be accessed on test point TP2. Refer to the schematic diagram in Figure 36.

The gain of OpAmp4 is determined by the ratio of the variable resistor RV1 and the resistor R157, as shown in the following equation:

Gain = 1+ RV1/R157

With the RV1 ranging from 0 to 10 kΩ and R157 being 1 kΩ, the gain can vary from 1 to 11.

The R158 resistor in series with PB12 is beneficial for reducing the output offset.

The DAC is exclusive with MC operation.

5.18 SRAM device

IS61WV51216BLL, an 8-Mbit static RAM (SRAM), 512K x16-bit, is fitted on the STM32G474E-EVAL main board, in U11 position. The STM32G474E-EVAL main board as well as the addressing capabilities of FMC allow hosting SRAM devices up to 64 Mbytes. This is the reason why the schematic diagram in Figure 30 mentions several SRAM devices.

The SRAM device is attached to the 16-bit data bus and accessed with FMC. The base address is 0x6000 0000, corresponding to NOR/SRAM1 bank1. The SRAM device is selected with FMC_NE1 chip select. FMC_NBL0 and FMC_NBL1 signals allow selecting 8-bit and 16-bit data word operating modes.

5.18.1 Limitations

The SRAM addressable space is limited if some or all of A20 FMC address lines is shunted to the CN17 connector for debug trace purposes. In such a case, the disconnected addressing inputs of the SRAM device are pulled down by resistors. Section 5.2 provides information on the associated configuration elements.

The SRAM is exclusive with MC operation.


The SRAM device operating voltage is in the range from 2.4 V to 3.6 V.

5.19 EXT_I2C connector

EXT_I2C connector CN1 can be connected to I²C bus daughter board. MFX_GPIO15 of MFX MCU provide EXT_RSET signal. And solder bridge SB1 is used to connector 5 V power supply for daughter board.

5.20 Quad-SPI Flash memory device

Two 512-Mbit Quad-SPI Flash memory device MT25QL512ABB8ESF-0SIT are fitted on the STM32G474E-EVAL main board, in U12 and U54 position. It allows evaluating STM32G474QET6U Quad-SPI interface.

5.20.1 Limitations

Quad-SPI Flash memory device operation is exclusive with motor control.


Voltage of Quad-SPI Flash memory device MT25QL512ABB8ESF-0SIT is in the range of 2.7 V to 3.6 V.

5.21 MFX MCU

The MFX MCU is used as MFX (Multi function expander) and IDD measurement.

5.21.1 MFX

MFX circuit on the STM32G474E-EVAL board acts as IO-expander. The communication interface between MFX and STM32G474QET6U is I2C3 bus. The signals connected to MFX are listed in Table 19.

5.21.2 IDD measurement

STM32G474QET6U has a built-in circuit to measure its own current consumption (IDD) in Run and Low-power modes, except for Shutdown mode. It is strongly recommended for the MCU supply voltage (VDD_MCU line) not to exceed 3.3 V. The reason is that there are components on the STM32G474E-EVAL supplied from 3.3 V, and they communicate with the MCU through I/O ports. Voltage exceeding 3.3 V on the MCU output port may inject current into 3.3 V-supplied peripheral I/Os and false the MCU current consumption measurement.

Table 20 shows settings of jumper associated with the IDD measurement on the board.

5.21.3 Limitations

1. The MFX is exclusive with Differential ADC and MC operation.

2. The IDD measurement operating voltage is in the range of 2.05 V to 3.6 V. This applies only to the MB1397-based boards within the following range of serial numbers:

– MB1397-G474E: A191000001 -A191000170

– MB1397-G474EMC: A191000001- A191000100

– MB1397-G484E: A191000001-A191000030

It can be used as bypass mode for normal MCU working. Refer to Table 20 for JP13 configuration.

5.22 TFT LCD panel

The STM32G474E-EVAL is delivered with MB895C, a daughterboard plugged into the CN20 and CN24 connectors. It bears a TFT 2.4-inch color TFT LCD panel with resistive touchscreen and an on-board controller. The TFT LCD connected to SPI2 port of the STM32G474QET6U.

Thanks to level shifters on all signal lines, the TFT LCD panel works with the entire operating voltage range of the STM32G474E-EVAL.

Note: The bi-directional voltage translator is implemented on SPI MOSI signal between the STM32G474QET6U and LCD to support 3-wires serial interface of LCD panel only supports

5.23 UCPD

5.23.1 USB Type-C receptacles

The USB Type-C certified receptacle CN22 is present on the STM32G474E-EVAL board. It can be used as DRP (Dual-Role Port), which is eligible to supply another platform plugged by a USB Type-C cable when they are configured as Provider or, otherwise, to be supplied in case of Consumer configuration.

The STM32G474E-EVAL board also supports USB2.0 compliant full speed communication via USB Type-C receptacle CN22.

5.23.2 Power Delivery & Local power management

The STM32G474E-EVAL board has its own external power jack (CN25, 5 V to 18 V input) with internal DC/DC regulator to support power delivery function and to provide up to 5.2 V / 3 A on Type-C receptacles (CN22). Please refer to Table 5 for JP12 setting selection.

5.23.3 VBUS management and discharge mechanism

Type-C receptacle (CN22) can be used as DRP (Dual-Role Port) Its VBUS can be managed for supplying other platforms as Provider, or to be supplied as Consumer. Two MOSFETs Q2 and Q3 are set in back-to-back configuration to protect and isolate the VBUS supplying path on both directions.

If the CN22 acts as Provider, the VBUS is on the supply path by mean of the discrete load switch (Q2 and Q3) driven by the STM32G474QET6U (GPIO, PC11). For the Consumer case, the same VBUS path is managed by PC11 of the STM32G474QET6U enabling the discrete load switch.

Moreover, the VBUS path on receptacle presents a discharge mechanism implemented by the MOSFET T9 and an RC filter and controlled by PB2.

5.23.4 VBUS voltage-sensing

Type-C receptacle (CN22) is equipped by a voltage-sensing stage which are matched with the voltage sensing carried by the STM32G474QET6U ADC port PC0. It can be able to monitor the right power level applied on the port VBUS.

5.23.5 CC management

Dead battery function is supported by embedded in the STM32G474QET6U, it can be enable or disable through enable signals by set JP15 (CC1) or JP14 (CC2). Refer to Table 22 for details.


42/83 UM2514 Rev 4

5.23.6 Limitations

UCPD operation is exclusive with motor control and JTAG JTRST signal PB4.

Due to the share of PA9 and PA10 terminals of the STM32G474QET6U by multiple peripherals, if USBPD use as part of USART1 port, it cannot be used as RS-232 or RS485 port and VCP peripheral.

Only SWD may be used for dead battery applications. It is impossible to use the JTAG due to the pull down on the PB4.

For no dead battery applications, the alternative to use the JTAG is:

• Either pulling low the DBCC2 pin (PA10)

• Or putting an external pull up on the PB4 (R183)

5.24 Temperature Sensor

A Temperature Sensor STTS751 is connected to I2C3 bus of the STM32G474QET6U, and shares same I2C3 bus with MFX, Audio and EXT_I2C connector.

I2C address of temperature sensor is 0x90 or 0x91.

Note: The temperature result measured from STTS751 may be a little higher than the ambient temperature due to the power dissipation of components on the board.


The temperature Sensor operating voltage is in the range from 2.25 V to 3.6 V.

5.25 Smartcard

STMicroelectronics smartcard interface chip ST8024L is used on the STM32G474E-EVAL evaluation board for asynchronous 1.8 V, 3 V and 5 V smartcards. It performs all supply protection and control functions based on the connections with STM32G474QET6U listed in Table 23.

The Smart card operating voltage is in the range from 2.7 V to 3.6 V.

5.26 High brightness LED

An Everluck company high brightness LED LE-CWC12100 and its power control circuits with the inverted buck topology are on the STM32G474E-EVAL board. The brightness can be adjusted by the PWM signal from STM32G474QET6U through PC8. The current on the LED can be monitored by the STM32G474QET6U thanks to the voltage measured on PB11, which corresponds to current through R177 (1 ohm). Please refer Table 16 for PB11 configuration.

5.26.1 Limitations

The high brightness LED is exclusive with OpAmp4/ Comp6 and MC operation.
