PCF8811
80 x 128 pixels matrix LCD driver
Rev. 6 10 February 2015 Product data sheet
1. General description
1
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 I C-bus interface.
For a selection of NXP LCD graphic drivers, see Table 44 on page 85.
