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.
