Description
The Intersil 82C54 is a high performance CMOS Program-
mable 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 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.
The Intersil advanced CMOS process results in a significant
reduction in power with performance equal to or greater than
existing equivalent products.
