ST7065C
40CH Segment/Common Driver for Dot Matrix LCD
Product Description
ST7065C is a segment/common driver for dot matrix type LCD display. It features 40 channels with 20 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 ST7065C can convert serial data received from a LCD controller, such as ST7066U, into parallel data and send out LCD driving waveforms to the LCD panel. The ST7065C is designed for general-purpose LCD drivers. It can drive both static and dynamic drive LCD. The LSI can be used as segment/common driver.
The ST7065C has pin function compatibility with the KS0065B that allows the user easily to replace it with a ST7065C.
