ST Sitronix INTRODUCTION ST7586S 4-Level Gray Scale Dot Matrix LCD Controller/Driver ST7586S is a driver & controller LSI for 4-level gray scale graphic dot-matrix liquid crystal display systems.
It contains 384-segment and 160-common driver circuits.
This chip can be connected directly to a microprocessor which accepts 8-bit parallel interface (8080-series or 6800-series type), 4-Line serial interface or 3-Line serial interface.
Display data is stored into an on-chip Display Data RAM (DDRAM).
It performs the Display Data RAM read/write operation without external operating clock, and the power consumption can be minimized.
In addition, since all necessary power supply circuits for LCD sy...
