LC868901/51
Row Driver IC for Dot Matrix Graphic LCD
Preliminary
Overview
The LC868901 sereis is a common driver for the liquid crystal dot-matrix graphic display. It generates 65 commons
maximum. The LC868901series has the RC-oscillator circuit attached resistor and the capacitor outside, and
generates the timing signals and LCD powers for the LC868900 segmentdrivers.
As the LC868901 series is fabricated using CMOS process technology, combining it with a CMOS microcontroller
produces an LCD device of low power demand.
