Overview

82C54 CMOS Programmable Interval Timer The 82C54 is a high performance CMOS Programmable Interval Timer manufactured using an advanced 2 micron CMOS process.
The 82C54 has three independently programmable and functional 16-bit counters, each capable of handling clock input frequencies of up to 8MHz (82C54) or 10MHz (82C54-10) or 12MHz (82C54-12).
The high speed and industry standard configuration of the 82C54 make it compatible with the 80C86, 80C88, and 80C286 CMOS microprocessors along with many other industry standard processors.
Six programmable timer modes allow the 82C54 to be used as an event counter, elapsed time indicator, programmable one-shot, and many other applications.
Static CMOS circuit design insures low power operation.
The advanced CMOS process results in a significant reduction in power with performance equal to or greater than existing equivalent products.
