The PCF8811 is a low-power CMOS LCD controller and driver. It is designed to drive a
graphic display of 80 rows and 128 columns or of 79 rows, 128 columns, and an icon row
of 128 symbols. All necessary functions for the display are provided in a single chip,
including on-chip generation of the LCD supply and bias voltages. Therefore only a
minimum of external components are required and power consumption is low. The
PCF8811 can interface microcontrollers via a parallel bus, serial bus, or I²C-bus interface.
