GENERAL DESCRIPTION
The OM6208 is a low power CMOS LCD controller driver,
designed to drive a graphic display of 65 rows and
96 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
OM6208 can be interfaced to microcontrollers via a serial
bus and I
2
C-bus.
The OM6208 is manufactured in n-well CMOS technology.
Operation is with the substrate at V
SS
potential.
