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.

FEATURES

? Single chip LCD controller/driver

? 48 row, 84 column outputs

? Display data RAM 48 × 84 bits

? On-chip:

– Generation of LCD supply voltage (external supply also possible)

– Generation of intermediate LCD bias voltages

– Oscillator requires no external components (external clock also possible).

? External RES (reset) input pin
