PCF8532  
Universal LCD driver for low multiplex rates  
Rev. 4 — 11 July 2013  
Product data sheet  
1. General description  
The PCF8532 is a peripheral device which interfaces to almost any Liquid Crystal Display  
(LCD)1 with low multiplex rates. It generates the drive signals for any static or multiplexed  
LCD containing up to four backplanes and up to 160 segments. It can easily be cascaded  
for larger LCD applications. The PCF8532 is compatible with most microcontrollers and  
communicates via the two-line bidirectional I2C-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).  
Not to be used for new designs. Replacement part is PCF85132U/2DA/1 for industrial and  
PCA85132U/2DA/Q1 for automotive applications.  
2. Features and benefits  
Single-chip LCD controller and driver for up to 640 elements  
Selectable backplane drive configuration: static, 2, 3, or 4 backplane multiplexing  
160 segment drives:  
Up to 80 7-segment numeric characters  
Up to 40 14-segment alphanumeric characters  
Any graphics of up to 640 elements  
May be cascaded for large LCD applications (up to 5120 elements possible)  
160 4-bit RAM for display data storage  
Software programmable frame frequency in steps of 5 Hz in the range of 60 Hz to  
90 Hz  
Wide LCD supply range: from 1.8 V for low threshold LCDs and up to 8.0 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 power supply range: from 1.8 V to 5.5 V  
LCD and logic supplies may be separated  
Low power consumption, typical: IDD = 4 A, IDD(LCD) = 30 A  
400 kHz I2C-bus interface  
Auto-incremental display data loading across device subaddress boundaries  
Versatile blinking modes  
Compatible with Chip-On-Glass (COG) technology  
Two sets of backplane outputs for optimal COG configurations of the application  
Display memory bank switching in static and duplex drive modes
