MSM82C54-2RS/GS/JS

CMOS PROGRAMMABLE INTERVAL TIMER

GENERAL DESCRIPTION

The MSM82C54-2RS/GS/JS is a programmable universal timer designed for use in

microcomputer systems. Based on silicon gate CMOS technology, it requires a standby current

of only 10 mA (max.) when the chip is in the non-selected state. And during timer operation, the

power consumption is still very low with only 10mA (max.) of current required.

It consists of three independent counters, and can count up to a maximum of 10 MHz. The timer

features six different counter modes, and binary count/BCD count functions. Count values can

be set in byte or word units, and all functions are freely programmable.
