GSM793E
Syntek Semiconductor Co., Ltd.
(80CH Segment Driver For Dot Matrix LCD)
Introduction :
GSM793E is a segment driver for dot matrix type LCD display. It features 80
channels with 40 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 GSM793E can convert serial data received from an LCD controller, such as
GSM7980, into parallel data and send out LCD driving waveforms to the LCD
panel. The GSM793E is designed for general purpose LCD drivers. It can drive
both static and dynamic drive LCD. The LSI can be used as segment driver.
The GSM793E has pin function compatibility with the KS0063(B) that allows
the user to easily replace it with an GSM793E.
