162 Color Dot Matrix LCD Controller/Driver
The ST7669V is a driver & controller LSI for 262K color graphic dot-matrix liquid crystal display systems. It generates 396
segments and 162 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface or 8-bit/16-bit/18-bit parallel 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.
