COP472-3 Liquid Crystal Display Controller
General Description
The COP472–3 Liquid Crystal Display (LCD) Controller is a peripheral member of the COPSTM family fabricated using
CMOS technology The COP472-3 drives a multiplexed liquid crystal display directly Data is loaded serially and is held in internal latches The COP472-3 contains an on-chip oscillator and generates all the multi-level waveforms for backplanes and segment outputs on a triplex display One COP472-3 can drive 36 segments multiplexed as 3 x 12 (4 digit display) Two COP472-3 devices can be used together to drive 72 segments (3 x 24) which could be an 8 digit display
