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.

Functional Description

General

The 82C54 is a programmable interval timer/counter

designed for use with microcomputer systems. It is a general

purpose, multi-timing element that can be treated as an

array of I/O ports in the system software.

The 82C54 solves one of the most common problems in any

microcomputer system, the generation of accurate time

delays under software control. Instead of setting up timing

loops in software, the programmer conﬁgures the 82C54 to

match his requirements and programs one of the counters

for the desired delay. After the desired delay, the 82C54 will

interrupt the CPU. Software overhead is minimal and vari-

able length delays can easily be accommodated.

Some of the other computer/timer functions common to micro-

computers which can be implemented with the 82C54 are:

•Real time clock

•Event counter

•Digital one-shot

•Programmable rate generator

•Square wave generator

•Binary rate multiplier

•Complex waveform generator

•Complex motor controller

With a wide supply voltage range from 5 V to 24 V, and the ability to operate on single supplies, with a bandwidth of 145 MHz, the AD8065-KGD-CHIP is designed to work in a variety of applications. For added versatility, the amplifier also features a rail-to-rail output. Despite the low cost, the amplifiers provide excellent overall performance. The differential gain and phase errors of 0.02% and 0.02°, respectively, along with 0.1 dB flatness out to 7 MHz, make these amplifiers ideal for video applications. Additionally, they offer a high slew rate of 180 V/µs, excellent distortion (SFDR of −88 dBc at 1 MHz), extremely high common-mode rejection of −100 dB, and a low input offset voltage of 1.5 mV maximum under warmed up conditions. The AD8065-KGD-CHIP operates using only a 6.4 mA/amplifier typical supply current and are capable of delivering up to 30 mA of load current. The AD8065-KGD-CHIP is rated to work over the industrial temperature range of −40°C to +85°C. Additional application and technical information can be found in the AD8065 data sheet.
