INTRODUCTION

S6B0708 is a single-chip LCD driver IC for liquid crystal dot-matrix graphic display systems. It incorporates 192 driver circuit for 64 common and 128 segment and 64 x 128-bit bit-map RAM. It is capable of interfacing with the microprocessor, accepting 8-bit parallel display data directly from it, and storing data in an one chip display data RAM. And it generates internal signals for using LCD driving independent of microprocessor clock.
