S6B0719中文资料三星数据手册PDF规格书

INTRODUCTION

The S6B0719 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 105 common and 160 segment driver circuits. This chip is connected directly to a microprocessor, accepts serial or 8-bit parallel display data and stores in an on-chip display data RAM of 105 x 160 bits. It provides a highly flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it performs display data RAM read/write operation with no external-operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
