2 GENERAL DESCRIPTION
The PCF8833 is a single chip low power CMOS LCD
controller driver, designed to drive colour Super-Twisted
Nematic (STN) displays of 132 rows and 132 RGB
columns. All necessary functions for the display are
provided in a single chip, including display RAM which has
a capacity of 209 kbit (132 × 12-bit × 132). The PCF8833
uses the Multiple Row Addressing (MRA) driving
technique in order to achieve the best optical performance
at the lowest power consumption. The PCF8833 offers
2 types of microcontroller interfaces namely the
8080 system interface and the 3-line serial interface.
