PCF8576E Universal LCD driver for low multiplex rates Rev. 1 22 January 2013 Product data sheet 1. General description The PCF8576E is a peripheral device which interfaces to almost any Liquid Crystal 1 Display (LCD) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 40 segments. It can be easily cascaded for larger LCD applications. The PCF8576E is compatible with most 2 microcontrollers and communicates via the two-line bidirectional I C-bus. Communication overheads are minimized by a display RAM with auto-incremented addressing, by hardware subaddressing and by display memory switching (static and duplex drive modes). 2. Features and benefits Single chip LCD controller and driver Selectable backplane drive configuration: static or 2, 3, 4 backplane multiplexing 1 1 Selectable display bias configuration: static, , or 2 3 Internal LCD bias generation with voltage-follower buffers 40 segment drives: Up to 20 7-segment numeric characters Up to 10 14-segment alphanumeric characters Any graphics of up to 160 elements 40 4-bit RAM for display data storage Auto-incremented display data loading across device subaddress boundaries Display memory bank switching in static and duplex drive modes Versatile blinking modes Independent supplies possible for LCD and logic voltages Wide power supply range: from 1.8 V to 5.5 V Wide logic LCD supply range: From 2.5 V for low-threshold LCDs Up to 6.5 V for high-threshold twisted nematic LCDs Low power consumption 2 400 kHz I C-bus interface May be cascaded for large LCD applications (up to 2560 elements possible) No external components required Compatible with chip-on-glass and chip-on-board technology Manufactured in silicon gate CMOS process 1.
