KS0108B
64CH SEGMENT DRIVER FOR DOT MATRIX LCD
INTRODUCTION
The KS0108B is a LCD driver LSl with 64 channel output
for dot matrix liquid crystal graphic display system. This
device consists of the display RAM, 64 bit data latch 64 bit
drivers and decoder logics. It has the internal display RAM
for storing the display data transferred from a 8 bit micro
controller and generates the dot matrix Iiquid crystal driv-
ing signals corresponding to stored data.The KS0108B
composed of the liquid crystal display system in combina-
tion with the KS0107B (64 common driver)
