www.DataSheet4U.com ST Sitronix 1. INTRODUCTION fewest components. ST7577 132 x 39 Dot Matrix LCD Controller/Driver ST7577 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. ST7577 contains 132 segment and 39 common driver circuits. This chip is connected directly to a microprocessor, accepts 3-line, 4-line serial peripheral interface (SPI) or 8-bit parallel interface, display data can stores in an on-chip Display Data RAM (DDRAM) of 132 x 39 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 2.
