Description
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).
