GENERAL DESCRIPTION
The OM6211 is a low power CMOS LCD row/column driver, designed to drive a dot matrix graphic display of
48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power
consumption. The OM6211 interfaces to microcontrollers via a 3-line serial interface.
