82C54

CMOS Programmable Interval Timer

March 1997

Features

Description

• 8MHz to 12MHz Clock Input Frequency

The Intersil 82C54 is a high performance CMOS Program-

mable Interval Timer manufactured using an advanced 2

micron CMOS process.

• Compatible with NMOS 8254

- Enhanced Version of NMOS 8253

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).

• Three Independent 16-Bit Counters

• Six Programmable Counter Modes

• Status Read Back Command

• Binary or BCD Counting

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.

• Fully TTL Compatible

• Single 5V Power Supply

• Low Power

• Operating Temperature Ranges

The Intersil advanced CMOS process results in a signiﬁcant

reduction in power with performance equal to or greater than

existing equivalent products.
