Description

The Harris 82C54 is a high performance CMOS Programma-

ble 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 Harris 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 Harris advanced CMOS process results in a signiﬁcant

reduction in power with performance equal to or greater than

existing equivalent products.
