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 Ч 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
