65K Color Dot Matrix LCD Controller/Driver

1. INTRODUCTION

The ST7530 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 256

Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral

Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. 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.

2. FEATURES
