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.
