· Telecom equipment. 3 GENERAL DESCRIPTION
The PCF8812 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 PCF8812 interfaces to microcontrollers via a serial bus interface.
