65K Color Dot Matrix LCD Controller/Driver

1. INTRODUCTION

The ST7624 is a driver & controller LSI for 65k color graphic dot-matrix liquid crystal display systems. It generates 312

Segment and 104 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral

Interface (SPI) or 8-bit/16-bit parallel 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.
