The S6B1713 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains  65 commons  and 132segmentsdriver circuits. This chip is connected directly to a microprocessor, accepts serial or 8-bit parallel display data and stores in an on-chip  Display Data RAM of  65x 132bits. It provides a high-flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it performs display data RAM read/write operation with no externally 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.
