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 x 12-bit x 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.
