CP82C54Z 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). The high-speed and industry-standard configuration of the 82C54 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. Static CMOS circuit design ensures low-power operation. The Intersil advanced CMOS process results in a significant reduction in power with performance equal to or greater than existing equivalent products.
