MC9S08L Family Features


S08 LCD family Features

�The S08 LCD family is built on the ultra low power platform which includes

� Low power oscillator

� Clock gating

� TOD for low power time keeping

� Low Power Run and Wait Modes

�In addition the LCD peripheral was built with low power considerations

� Low power LCD waveforms

� Efficient charge pump to produce LCD bias voltages

�Altogether these features make the S08 LCD family the lowest power LCD microcontroller!


Key Differentiating Features

► LL devices� Ultra-Low-Power Provides Longer battery life for both S08 and

32-bit devices

� FSL devices keep high performance while using low voltage� FSL can run at 10 MHz bus frequency at less voltage

– Benefit: Perform tests and operations faster– FSL Is maximized to run at top frequency no matter the voltage

� Flash programming at 1.8V while competitors’ lowest is 2.2V– If working off batteries, with FSL part customer can re-program flash.– Ability to update variables/constants and provides greater flexibility

► Can save variables to flash before batteries die and are replaced► Can perform field s/w upgrades at any time, doesn’t require fresh batteries► If working with a competitor device, customer cannot re-program flash

� Target Applications:– Medical instrumentation– Metering– Handheld devices

Low power features - TOD time outs

• TOD max time out is 64 seconds � Competitors have shorter time outs (8s)

� Longer time outs lead to less average power consumption

� TOD can remain in stop for 1 minute, then wake to update the time display

LCD Power supply configurations and application hints


S08LL LCD family Power Supply features

The VSUPPLY[1:0] is used to Configure internal switches that Select the LCD charge pump Power source

The LCD charge pump can take in VLL1, VLL2 or VLL3 and produce the Other LCD bias voltages needed to Drive the LCD glass

Charge pump Select (CPSEL) is used to select from the Resistor bias network or the charge pump output

Other configuration bits are used to configure 3 or 5V glass operation and VLCD buffered or unbuffered modes


S08LL LCD family Power Supply features

The LCD section of the reference manual contains a table that shows all of the available LCD operation states.

The 13 operational states can be configured to support 3 or 5V glass to support over 25 configurations.


Average Power consumption with different LCD Supply configurations

Lowest power mode


Factors that will affect LCD standby current

Number of segments supported – More segments will lead to higher power consumption.

Temperature - Due to leakage at high temperatures, there is a sharp increase after 70C.

Glass Voltage – When supporting 5V glass, the power consumption will increase due to the increased demands to the LCD charge pump.



LCD Frame Rate – Frame rate is the rate at which the LCD segments will be refreshed. Frame rates that are too fast will produce ghosting, frame rates that are too slow will have poor contrast.

. LCD Peripheral allows for configurable frame rate.

Using the LCLK bits the frame rate can be optimized

for the custom glass.



LCD Glass Capacitance - LCD glass capacitance is determined by the area of the segments on the glass. The larger the segment area, the larger the Capacitance will be.

500pF glass

8000pF glass


Reaching for even lower power: Use Blink Mode

Benefits of using blink mode

1- Blinking to a blank screen turns all segments off, leading to lower standby current for the time that the screen is blank

2 - Using the Alternate blink mode allows the application to remain in Stop mode for longer periods of time.Example: Using alternate display to show time across 2 Seconds
