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:

– Oscillator for display system, requires no external

components (external clock also possible)

– Generation of VLCD

– Segmented temperature compensation of VLCD and

frame frequency.

• Logic supply voltage range VDD1 to VSS1:

– 1.5 to 3.3 V.

• Analog supply voltage range for VLCD generation VDD2

to VSS2:

– 2.4 to 4.5 V.

• Analog supply voltage range for reference voltage

generation VDD3 to VSS1:

– 2.4 to 3.5 V.

• Display supply voltage range VLCD to VSS1:

– 3.8 to 20 V.

• Low power consumption; suitable for battery operated

systems

• CMOS compatible inputs

• Manufactured in silicon gate CMOS process

• Optimized layout for COF, Chip On Glass (COG) and

Transformer Coupled Plasma (TCP) assembly.

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.
