www.DataSheet4U.com TECHNICAL DATA Liquid Crystal Display Controller The KK472 Liquid Crystal Display (LDC) Controller is a perpheral member of the COPSTM family, fabricated using CMOS technology.

The KK472 drives a multiplexed liquid crystal directly.

Data is loaded serially and is held in internal latches.

The KK472 contains an on-chip oscillator and generates all the multi-level waveforms for back-planes and segment outputs on a triplex display.

One KK472 can drive 36 segments multiplexed a
