CMOS Programmable Intervel Timer

The NEC uPD71054 is a high performance CMOS
Programmable Interval Timer manufactured using an
advanced 2 micron CMOS process.
The uPD71054 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
uPD71054 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 uPD71054 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 NEC advanced CMOS process results in a significant
reduction in power with performance equal to or greater than
existing equivalent products.
