The Intersil 82C59A is a high performance CMOS Priority
Interrupt Controller manufactured using an advanced 2µm
CMOS process. The 82C59A is designed to relieve the sys-
tem CPU from the task of polling in a multilevel
priority system. The high speed and industry standard
configuration of the 82C59A make it compatible with micro-
processors such as 80C286, 80286, 80C86/88, 8086/88,
8080/85 and NSC800.
The 82C59A can handle up to eight vectored priority inter-
rupting sources and is cascadable to 64 without additional
circuitry. Individual interrupting sources can be masked or
prioritized to allow custom system configuration. Two modes
of operation make the 82C59A compatible with both 8080/85
and 80C86/88/286 formats.
Static CMOS circuit design ensures low operating power.
The Intersil advanced CMOS process results in performance
equal to or greater than existing equivalent products at a
fraction of the power.
