M82C54-2 - 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.

Key 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.

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.
