PCF8533 Universal LCD driver for low multiplex rates Rev. 6 1 October 2012 Product data sheet 1. General description The PCF8533 is a peripheral device which interfaces to almost any Liquid Crystal Display 1 (LCD) with low multiplex rates. It generates the drive signals for any static or multiplexed LCD containing up to four backplanes and up to 80 segments and can easily be cascaded for larger LCD applications. The PCF8533 is compatible with most microcontrollers and 2 communicates via the two-line bidirectional I C-bus. Communication overheads are minimized by a display RAM with auto-incremental 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, 2, 3, or 4 backplane multiplexing 1 1 Selectable display bias configuration: static, ,or 2 3 Internal LCD bias generation with voltage follower buffers 80 segment outputs allowing to drive: 40 7-segment alphanumeric characters 20 14-segment alphanumeric characters Any graphics of up to 320 elements 80 4 bit RAM for display data storage Auto-incremental 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 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 5120 elements possible) No external components required Compatible with Chip-On-Glass (COG) technology Manufactured using silicon gate CMOS process 1.
