GENERAL DESCRIPTION
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 columnsandaiconrowof128 symbols.Allnecessary
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
to microcontrollers via a parallel bus, serial bus or I
