ST7545T规格书详情
INTRODUCTION
The ST7545T is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segments and 65 commons with 1 ICON driver circuits. This chip is connected directly to a microprocessor, accepts 8-bit parallel interface、3-line or 4-line serial peripheral interface (SPI)、I2C interface, display data can stores 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.
