CP82C54-10 CMOS Programmable Interval Timer - (AD11639)

Description:

The Intersil 82C54 is a high performance CMOS programmable interval timer, manufactured using an advanced CMOS process. The 82C54 has three independently programmable and functional 16-bit counters, each capable of handling clock input frequencies up to 8MHz (82C54) or 10MHz (82C54-10) or 12MHz (82C54-12). The 82C54's industry standard high speed configuration makes it compatible with the Intersil 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. CMOS circuit design ensures low power operation. The advanced Intersil CMOS process results in a significant reduction in power with performance equal to or greater than existing equivalent products.
