PCF8534A
Universal LCD driver for low multiplex rates
Rev. 00.90 — 4 February 2008
Product data sheet
1. General description
The PCF8534A is a peripheral device which interfaces to almost any Liquid Crystal
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 60 segments and can easily
be cascaded for larger LCD applications. The PCF8534A is compatible with most
microprocessors / microcontrollers and communicates via a two-line bidirectional I2C-bus.
Communication overheads are minimized using a display RAM with auto-incremented
addressing, hardware subaddressing and display memory switching (static and duplex
drive modes).
2. Features
Single-chip LCD controller / driver
Selectable backplane drive configuration: static or 2 / 3 / 4 backplane multiplexing
60 segment drives: up to thirty 8-segment numeric characters; up to sixteen
15-segment alphanumeric characters; or any graphics of up to 240 elements
May be cascaded for larger applications
60 × 4-bit RAM for display data storage
Wide LCD supply range: from 2.5 V for low threshold LCDs and up to 6.5 V for
guest-host LCDs and high threshold (automobile) twisted nematic LCDs
Internal LCD bias generation with voltage-follower buffers
Selectable display bias configuration: static, 1⁄2 or 1⁄3
Wide logic power supply range: from 1.8 to 5.5 V
LCD and logic supplies may be separated
