STN RGB - 132 × 132 × 3 driver
Objective specification
PCF8833
1 FEATURES
• Single chip LCD controller and driver
• 132 rows and 396 column outputs (132 × RGB)
• Low cross talk by Frame Rate Control (FRC)
• 4 kbyte colours (RGB) = 4 : 4 : 4 mode
• 256 colours (RGB) = 3 : 3 : 2 mode using the 209 kbit
RAM and a Look-Up Table (LUT)
• 65 kbyte colours (RGB) = 5 : 6 : 5 mode using the
209 kbit RAM with dithering
• 8 colours Power-save mode
• Display data RAM 132 × 132 (RGB) (4 kbyte colour)
• Interfaces:
– 3-line serial interface
– 8-bit 8080 Intel CPU interface.
• Display features:
– Area scrolling
– 32-line partial Display mode
– Software programmable colour depth mode
– N-line inversion for low cross talk.
• On-chip:

Transformer Coupled Plasma (TCP) assembly.
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.
