PCF8534  
Universal LCD driver for low multiplex rates  
Rev. 00.05 — 20 February 2007  
Preliminary datasheet  
1. General description  
The PCF8534 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 PCF8534 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  
„ Selectable display bias configuration:  
static, 12 or 13  
„ Internal LCD bias generation with  
voltage-follower buffers  
„ 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  
„ 60 x 4-bit RAM for display data storage  
„ Auto-incremented display data loading „ Display memory bank switching in static  
across device subaddress boundaries  
and duplex drive modes  
„ Versatile blinking modes  
„ LCD and logic supplies may be  
separated  
„ Wide power supply range: from  
„ 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  
1.8 to 5.5 V  
„ Low power consumption  
„ TTL/CMOS compatible  
„ 400 kHz I2C-bus interface  
„ Compatible with 4-bit, 8-bit or 16-bit  
microprocessors/microcontrollers  
„ May be cascaded for 2 LCD applications „ No external components  
„ Manufactured in silicon gate CMOS  
process.
