Renesas Electronics CP82C54 CP82C54-10Z, Programmable Timer, 6 10MHz, 24-Pin PDIP

The Renesas Electronics 82C54 is a high performance CMOS programmable interval timer manufactured using an advanced 2 micron CMOS process. Six programmable timer modes allow the 82C54 to be used as an event counter, elapsed time indicator, programmable one-shot, and many other applications. The intersil advanced CMOS process results in a significant reduction in power with performance equal to or greater than existing equivalent products.
