INTRODUCTION

KS0708 is a single-chip LCD driver LSI for liquid crystal dot-matrix graphic display systems. It incorporates

192 driver circuit for 64 commom and 128 segment and 64x128-bit bit-map RAM. It is capable of interfac-

ing with the microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an

onechip Display Data RAM. And it generates internal signals for using LCD driving independent of micro-

processor clock.
