CMOS Programmable Interval Timer

The Intersil 82C54 is a high performance CMOS

Programmable Interval Timer manufactured using an

advanced 2 micron CMOS process.

Features

• 8MHz to 12MHz Clock Input Frequency

• Compatible with NMOS 8254

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).

- Enhanced Version of NMOS 8253

• 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

The Intersil advanced CMOS process results in a significant

reduction in power with performance equal to or greater than

existing equivalent products.
