4K Color Dot Matrix LCD Controller/Driver

1. INTRODUCTION

The ST7632 is a driver & controller LSI for 4K color graphic dot-matrix liquid crystal display systems. It generates 396

Segment and 132 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.

On-chip Low Power Analog Circuit

2. FEATURES

- On-chip oscillator circuit

Driver Output Circuits
