3 / 112 page 2003 Feb 14 3 Philips Semiconductors Objective specification STN RGB - 132 × 132 × 3 driver 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: – 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. 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. 3 ORDERING INFORMATION TYPE NUMBER PACKAGE NAME DESCRIPTION VERSION PCF8833U/2DA/1 − chip with bumps in tray − |
