ST Sitronix 1. INTRODUCTION ST7626 65K Color Dot Matrix LCD Controller/Driver The ST7626 is a driver & controller LSI for 65K color graphic dot-matrix liquid crystal display systems. It generates 294 Segment and 68 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. 2.
