68 x 102 Dot Matrix LCD Controller/Driver
Ver 2.0 1/72 2003/5/10
1. INTERODUCTION
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
circuits to drive liquid crystal, it is possible to make a display system with the fewest components.
