COP472-3 Liquid Crystal Display Controller
General Description
The COP472–3 Liquid Crystal Display (LCD) Controller is a
peripheral member of the COPS
TM
family, fabricated using
CMOS technology. The COP472-3 drives a multiplexed liq-
uid crystal display directly. Data is loaded serially and is held
in internal latches. The COP472-3 contains an on-chip oscil-
lator 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 as 3 x 12
(4
(/2
digit display). Two COP472-3 devices can be used to-
gether to drive 72 segments (3 x 24) which could be an 8
(/2
digit display.
