I am using MC9S08LG32 (LQFP-80 package) with inbuilt LCD Module.
I am operating my core and other peripherals at 3.3 VDC.
Can I still operate my LCD Module from 5 VDC power-rail without damaging the controller.
The LG32 has an integrated LCD driver that can supply LCD waveforms for 5 V glass. You can use the on-chip charge pump to create the 5V source needed to drive the LCD when operating the MCU at 3.3V.
The only time you should connect VLL3 to 5 V is when the MCU voltage is set at 5 V.
The externally supplied voltages MUST NOT EXCEED VDD .
Check out the reference manual, LCD section
Table 9-19. LCD Power Supply Options.
