ST7549T Datasheet | Sitronix Technology

Sitronix 68 x 102 Dot Matrix LCD Controller/Driver 1. INTRODUCTION The ST7549T is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segment and 67 mon with 1 ICON driver circuits. This chip is connected directly to a microprocessor, accepts 3-line or 4-line serial peripheral interface (SPI), I2C interface or 8-bit parallel interface, display data can stores in an on-chip display data RAM of 68 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...
