ST7546T

66 x 102 Dot Matrix LCD Controller/Driver

1. INTRODUCTION

The ST7546T is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segment

and 65 common with 1 ICON driver circuits. This chip is connected directly to a microprocessor, accepts 8-bit parallel

interface、3-line or 4-line serial peripheral interface (SPI)、I²C interface, display data can stores in an on-chip display

data RAM of 66 x 102 bits. 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 to drive liquid crystal, it is possible

to make a display system with the fewest components.
