This datasheet describes the Sitronix ST7580A, a single-chip LSI for graphic dot-matrix LCD systems featuring built-in oscillation and low power consumption.
The ST7580A is a single-chip Large Scale Integration (LSI) designed specifically for graphic dot-matrix Liquid Crystal Display (LCD) systems. It integrates an LCD controller, drivers, and a complete power system into one package. The device can be connected directly to a microprocessor supporting either an 8-bit parallel interface or a 4-line serial interface (SPI-4). Internal display data is stored in the on-chip Display Data RAM (DDRAM) with a capacity of 160 x 84 bits, allowing direct control of pixels on the LCD panel.
The on-chip Display Data RAM has a capacity of 160 x 84 = 12,960 bits.
The maximum LCD Vop is 18V.
The typical operation range is 6V to 17V.
