MSM82C54-2RS/GS/JS
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.
FEATURES

Completely static operation
Three independent 16-bit down-counters
Status Read Back Command
Six counter modes available for each counter
Binary and decimal counting possible
