The PCF8548 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 PCF8548 interfaces to most microcontrollers via an I2C-bus interface. 3.1 Packages
The PCF8548 is available as chip with bumps in tray; tape carrier package is available on request.
