Description
80 x 128 pixels matrix LCD driver
Manufacturer
NXP [NXP Semiconductors]
Datasheet
1. General description
2. Features
The PCF8811 is a low-power CMOS LCD controller driver, designed to drive a graphic
display of 80 rows and 128 columns or a graphic display of 79 rows and 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, resulting in a
minimum of external components and low power consumption. The PCF8811 can
interface microcontrollers via a parallel bus, serial bus or I
