capable of handling clock input frequencies of up to 8MHz (82C54) or 10MHz (82C54-10)
or 12MHz (82C54-12).
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 insures low power operation.
