Description
!"
ST7063C 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 ST7063C can convert serial data received from an LCD controller, such as ST7066U, into parallel data and send out LCD driving waveforms to the LCD panel. The ST7063C 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 ST7063C has pin function patibility with the KS0063(B) that allows the user to easily replace it with an ST7063C.
