GENERAL DESCRIPTION

The PCF8549 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 PCF8549 interfaces to most microcontrollers via an

I2C interface.
