资 源 简 介
The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255 Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), 8-bit/16-bit parallel or IIC 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.
