Description

The MSM82C54-2R3 is a programmable universal timer designed for use in microcomputer systems. It is based on silicon gate CMOS technology, which allows for high speed and low power consumption. The chip only requires a standby current of 10 mA (max.) in the non-selected state and maintains low power consumption during timer operation. It features three independent counters and can count up to a maximum of 10 MHz. With six different counter modes and the ability to count in binary or BCD, it offers versatile functionality. The chip is available in three different package options: 24-pin Plastic DIP (DIP24-P-600-2.54), 28-pin Plastic QFJ (QFJ28-P-S450-1.27), and 32-pin Plastic SSOP (SSOP32-P-430-1.00-K).
