On-chip Low Power Analog Circuit
The ST7576 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 102 segments
and 65 common with 1 ICON driver circuits. This chip is connected directly to a microprocessor, accepts 3-line or 4-line
serial peripheral interface (SPI), I
data RAM 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.
