Overview
ST Sitronix INTRODUCTION ST7528 16 Gray Scale Dot Matrix LCD Controller/Driver The ST7528 is a driver & controller LSI for 16-level gray scale graphic dot-matrix liquid crystal display systems.
It contains 2 Mode (160X100,132X128) for Segment and Common driver circuits.
This chip is connected directly to a microprocessor, accepts Serial Peripheral Interface (SPI), IIC or 8-bit parallel display data and stores in an on-chip display data RAM of 160 x 129 x 4 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 necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
