1. General Description
The RA8808 is a LCD driver LSI with 128(Segment) x 64(Common) driver output for dot matrix liquid crystal
graphic display systems. This device consists of the display RAM,128-bit segment drivers, 64-bit common
drivers and decoder logic. It has the internal display RAM for storing the display data transferred from an 8-
bit 8080/6800 micro controller or 3-wire-SPI/IIC controller and generates the dot matrix liquid crystal driving signals corresponding to stored data.

2. Features
Dot matrix LCD segment driver with 128
  channel output, and common driver with 64 channel output.
Internal timing generator circuit for dynamic display.
Selection of master/slave mode for combine two RA8808 controller to support 256x64 dot Matrix.
