描述 Description

INTRODUCTION
The ST7669 is a driver & controller LSI for 262K color graphic dot-matrix liquid crystal display systems. It generates 396 Segment and 162 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI) or 8-bit/16-bit/18-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.FEATURES
