GENERAL DESCRIPTION
The PCD8544 is a low power CMOS LCD controller/driver,
designed to drive a 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 PCD8544 interfaces to microcontrollers through a
serial bus interface.
The PCD8544 is manufactured in n-well CMOS
technology.
