The 82C54 is pin compatible with the HMOS 8254, and is a superset of the 8253. Six programmable timer modes allow the 82C54 to be used as an event counter, elapsed time indicator, programmable one-shot, and in many other applications.
Intel TP82C54 programmable timer re-introduced by Rochester
Rochester Electronics re-introduces the Intel 82C54 high-performance, CHMOS version of the industry standard 8254 counter/timer. Designed to solve the timing control problems common in microcomputer system design, this device provides three independent 16-bit counters, each capable of handling clock inputs up to 10MHz. All modes are software programmable.
