Product Summary

The COP472N-3 is a Liquid Crystal Display (LCD) Controller. It drives a multiplexed liquid crystal display directly. Data is loaded serially and is held in internal latches. The device contains an on-chip oscillator and generates all the multi-level waveforms for backplanes and segment outputs on a triplex display. One COP472N-3 can drive 36 segments multiplexed as 3x12 (4 1/2 digit display). Two COP472N-3 devices can be used together to drive 72 segments (3 x 24) which could be an 8 1/2 digit display.

Parametrics

COP472N-3 absolute maximum ratings: (1)Voltage at CS, DI, SK pins:-0.3V to +9.5V; (2)Voltage at all other Pins:-0.3V to VDD+0.3V; (3)Operating Temperature Range:0℃ to 70℃; (4)Storage Temperature:-65℃to +150℃; (5)Lead Temp. (Soldering, 10 Seconds):300℃.

Features

COP472N-3 features: (1)Direct interface to TRIPLEX LCD; (2)Low power dissipation (100 mW typ.); (3)Low cost; (4)Compatible with all COPS processors; (5)Needs no refresh from processor; (6)On-chip oscillator and latches; (7)Expandable to longer displays; (8)Operates from display voltage; (9)MICROWIRE compatible serial I/O; (10)20-pin Dual-In-Line package and 20-pin SO.
