INTEGRATED CIRCUITS DATA SHEET PCF8801 LCD driver for 140 × 2 segments Product specification File under Integrated Circuits, IC12 2000 Feb 04 Philips Semiconductors Product specification LCD driver for 140 × 2 segments FEATURES Single-chip LCD controller/driver Fixed backplane multiplexing at a rate of 1 : 2 Internal LCD bias generation (0.5VDD) 140 segment outputs configured to drive seven 40-segment characters On-chip oscillator with one external resistor Wide power supply range (2.7 V up to 5.5 V) Low power consumption Compatible with most microprocessors/microcontrollers 1 MHz serial bus interface (280-bit shift register) Easily cascaded for large LCD applications (two cascade directions possible) Compatible with chip-on-glass technology Manufactured by silicon gate CMOS process. GENERAL DESCRIPTION The PCF8801 is a peripheral device which interfaces a multiplexed Liquid Crystal Display (LCD) having two backplanes and up to 140 segments. It generates drive signals at a multiplex rate of 1 : 2 allowing seven 40-segment (5 x 8) characters to be driven. ORDERING INFORMATION TYPE NUMBER PCF8801U PACKAGE NAME − chip with bumps in tray DESCRIPTION PCF8801 The chip can easily be cascaded for larger LCD applications, and the direction of the information flow in the cascade can be selected. The PCF8801 is compatible with most microprocessors/microcontrollers and communicates via a serial bus interface comprising a 280-bit shift register. The outputs are...
