General Description :
ST7921 is a segment driver for dot matrix type LCD display. It features 96 channels
with 48 X 2 bits bi-directional shift registers, data latches, LCD drivers and logic
control circuits. It is fabricated by high voltage CMOS process with low current
consumption.
The ST7921 can convert serial data received from an LCD controller, such as ST7920,
into parallel data and send out LCD driving waveforms to the LCD panel. The
ST7921 is designed for general purpose LCD drivers. It can drive both static and
dynamic drive LCD. The LSI can be used as segment driver.
