GENERAL DESCRIPTION
The PCF8558 is a low power CMOS LCD controller driver,
designed to drive a graphic display of 40 rows and
101 columns. All necessary functions for the display are
provided in a single chip, including on-chip generation of
LCD bias voltages, resulting in a minimum of external
components and lower power consumption.
