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.
