S6B0741 128 SEG / 129 COM DRIVER & CONTROLLER FOR STN LCD
1
INTRODUCTION
The S6B0741 is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems. It
contains 128 segment and 129 common driver circuits. This chip is connected directly to a microprocessor, accepts
Serial Peripheral Interface (SPI) or 8-bit parallel display data and stores in an on-chip display data RAM of 128 x 129
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 necessary to drive liquid crystal, it is possible to
make a display system with the fewest components.
