ST7586S
16-Level Gray Scale Dot Matrix LCD Controller/Driver
INTRODUCTION
ST7586S is a driver & controller LSI for 16-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 system are built-in, ST7586S constructs a LCD display system with the fewest components.
