COP472WM-3 Datasheet PDF - TI

●General Description

●The COP472± 3 Liquid Crystal Display (LCD) Controller is a peripheral member of the OPSTM 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 back planes and segment outputs on a triplex display. One COP472-3 can drive 36 segments multiplexed as3x12 (4(/2digit display). Two COP472-3 devices can be used to gether to drive 72 segments (3 x 24) which could be an 8 1/2 digit display.
