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, 12 or 13  
„ Wide logic power supply range: from 1.8 to 5.5 V  
„ LCD and logic supplies may be separated  
„ Low power consumption  
„ 400 kHz I2C-bus interface  
„ Compatible with 4-bit, 8-bit or 16-bit microprocessors/microcontrollers  
„ No external components  
„ Display memory bank switching in static and duplex drive modes  
„ Auto-incremented display data loading across device subaddress boundaries  
„ Versatile blinking modes  
„ TTL/CMOS compatible  
„ Manufactured in silicon gate CMOS process  
„ Automotive AEC-Q100 compliant.
