GENERAL DESCRIPTION
The PCF8548 is a low power CMOS LCD controller driver,
designed to drive a graphic display of 65 rows and
102 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 PCF8548 interfaces to most microcontrollers via an
I
2
C-bus interface.
