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 as 3 x 12 (41/2 digit display). Two KK472 devices can be used together to drive 72 segments (3 x 24) which could be an 81/2 digit display. • • • • • • • • • • • Direct interface to TRIPLEX LCD Low power dissipation (100 µW typ.
