INTRODUCTION
ST7575
66 x 102 Dot Matrix LCD Controller/Driver
ST7575 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems.
It contains 102-segment and 65-common with 1-icon-common driver circuits.
This chip is connected directly to a microprocessor which accepts 3-line or 4-line serial peripheral interface (SPI) or 8-bit parallel interface.
Display data stores in an on-chip display data RAM (DDRAM) of 66 x 102 bits.
It performs display data RAM read/write operation with no external operating clock to minimize power consumption.
In addition, because it contains power supply circuits to drive liquid crystal, it is possible to make a display system with the fewest components.
