Sitronix 1. INTERODUCTION circuits to drive liquid crystal, it is possible to make a display system with the fewest components. ST7568 68 x 102 Dot Matrix LCD Controller/Driver The ST7568 is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems. It contains 102 segment and 68 common driver circuits. This chip is connected directly to a microprocessor, accepts. 4-line serial interface(SPI) or 8-bit parallel interface or IIC serial interface, display data can stores in an on-chip display data RAM of 68 x 102 x 2 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 2.
