... SDA V SS 2002 Jan 17 9 FUNCTIONAL DESCRIPTION The OM6211 is a low power LCD driver designed to interface with microprocessors/microcontrollers and a wide variety of LCDs. The host microprocessor or microcontroller and the OM6211 are connected via a serial interface. The internal oscillator requires no external components. The appropriate intermediate bias voltages for the multiplexed LCD waveforms are generated on-chip ...
