GENERAL DESCRIPTION
The PCF8832 column driver is a low power CMOS LCD
controller, column driver and power supply controller that
drives colour STN displays together with a suitable row
driver. The column driver offers four microcontroller
interfaces (8080-type system, 6800-type system, SPI and
I
2
C-bus).
