ST Sitronix 1. INTRODUCTION ST7556 65 x 102 Dot Matrix LCD Controller/Driver The ST7556 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segment and 65 common with 1 ICOM driver circuits. This chip is connected directly to a microprocessor, accepts 4-line serial interface (SPI) or 8-bit parallel interface, display data can store 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. 2.
