PCF8579  
LCD column driver for dot matrix graphic displays  
Rev. 05 — 11 May 2009  
Product data sheet  
1. General description  
The PCF8579 is a low power CMOS1 LCD column driver, designed to drive dot matrix  
graphic displays at multiplex rates of 1:8, 1:16, 1:24 or 1:32. The device has 40 outputs  
and can drive 32 × 40 dots in a 32 row multiplexed LCD. Up to 16 PCF8579s can be  
cascaded and up to 32 devices may be used on the same I2C-bus (using the two slave  
addresses). The device is optimized for use with the PCF8578 LCD row/column driver.  
Together these devices form a general purpose LCD dot matrix driver chip set, capable of  
driving displays of up to 40960 dots. The PCF8579 is compatible with most  
microcontrollers and communicates via a two-line bidirectional bus (I2C-bus). To allow  
partial VDD shutdown the ESD protection system of the SCL and SDA pins does not use a  
diode connected to VDD. Communication overhead is minimized by a display RAM with  
auto-incremented addressing and display bank switching.  
2. Features  
I LCD column driver  
I Used in conjunction with the PCF8578, this device forms part of a chip set capable of  
driving up to 40960 dots  
I 40 column outputs  
I Selectable multiplex rates; 1:8, 1:16, 1:24 or 1:32  
I Externally selectable bias configuration, 5 or 6 levels  
I Easily cascadable for large applications (up to 32 devices)  
I 1280-bit RAM for display data storage  
I Display memory bank switching  
I Auto-incremented data loading across hardware subaddress boundaries (with  
PCF8578)  
I Power-On Reset (POR) blanks display  
I Logic voltage supply range 2.5 V to 6 V  
I Maximum LCD supply voltage 9 V  
I Low power consumption  
I I2C-bus interface  
I Compatible with most microcontrollers  
I Optimized pinning for single plane wiring in multiple device applications (with  
PCF8578)  
I Space saving 56-lead small outline package and 64-pin quad flat pack
