PCF8534A  
Universal LCD driver for low multiplex rates  
Rev. 05 — 6 August 2009  
Product data sheet  
1. General description  
The PCF8534A is a peripheral device which interfaces to almost any LCD1 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. In addition, the PCF8534A can be easily  
cascaded for larger LCD applications. The PCF8534A is compatible with most  
microprocessors or microcontrollers and communicates via a two-line bidirectional  
I2C-bus. Communication overheads are minimized using display RAM with  
auto-incremented addressing, hardware subaddressing and display memory switching  
(static and duplex drive modes).  
The PCF8534AH only complies with the AEC-Q100 automotive qualification standard.  
2. Features  
I Single-chip LCD controller and driver  
I Selectable backplane drive configurations: static or 2, 3 or 4 backplane multiplexing  
I 60 segment outputs allowing to drive:  
N 30 7-segment numeric characters  
N 16 14-segment alphanumeric characters  
N Any graphics of up to 240 elements  
I Cascading supported for larger applications  
I 60 × 4-bit display data storage RAM  
I Wide LCD supply range: from 2.5 V for low threshold LCDs up to 6.5 V for guest-host  
LCDs and high threshold (automobile) twisted nematic LCDs  
I Internal LCD bias generation with voltage follower buffers  
I Selectable display bias configurations: static, 12 or 13  
I Wide logic power supply range: from 1.8 V to 5.5 V  
I LCD and logic supplies may be separated  
I Low power consumption  
I 400 kHz I2C-bus interface  
I Compatible with any microprocessors or microcontrollers  
I No external components  
I Display memory bank switching in static and duplex drive modes  
I Auto-incremented display data loading  
I Versatile blinking modes  
I Silicon gate CMOS process
