PCF8558 Description
GENERAL DESCRIPTION PCF8558 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 ponents and lower power consumption. The PCF8558 interfaces to most microcontrollers via a I2C-bus interface.
