3 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.
