65K Color Dot Matrix LCD Controller/Driver

1. INTRODUCTION

The ST7628 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 294

Segment and 70 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.

♦ 3-line (9-bits) serial interface

2. FEATURES

with internal booster capacitors.

♦ Various Partial Display

♦ Partial Window Moving & Data Scrolling

Gray-Scale Display

♦ Extremely Few Outsider Components. (Required

outsider components: Three Capacitors)

♦ On-chip Voltage Regulator

♦ 4FRC & 31 PWM function circuit to display 64

gray-scale display

♦ On-chip Electronic Contrast Control Function
