4 / 71 page  S6B0723 PRELIMINARY SPEC. VER. 0.9 65 COM / 132 SEG DRIVER & CONTROLLER FOR STN LCD 1 INTRODUCTION The S6B0723 is a single-chip driver & controller LSI for graphic dot-matrix liquid crystal display systems. This chip can be connected directly to a microprocessor, accepts serial or 8-bit parallel display data from the microprocessor, stores the display data in an on-chip display data RAM of 65 x 132 bits and generates a liquid crystal display drive signal independent of the microprocessor. It provides a high-flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. It contains 65 common driver circuits and 132 segment driver circuits, so that a single chip can drive a 65 x 132 dot display. And the capacity of the display can be increased through the use of master/slave multi-chip structures. This chip is able to minimize power consumption because it performs display data RAM read/write operation with no external operation clock. In addition, because it contains power supply circuits necessary to drive liquid crystal, which is a display clock oscillator circuit, high performance voltage converter circuit, high-accuracy voltage regulator circuit, low power consumption voltage divider resistors and OP-Amp for liquid crystal driver power voltage, it is possible to make the lowest power consumption display system with the fewest components for high performance portable systems. FEATURES Display Driver Output Circuits − 65 common outputs / 132 segment outputs On-chip Display Data RAM − Capacity: 65 x 132 = 8,580 bits − RAM bit data “1”: a dot of display is illuminated. − RAM bit data “0”: a dot of display is not illuminated.
