Sep 8, 2015 CMOS Priority Interrupt Controller
The Intersil 82C59A is a high performance CMOS Priority
Interrupt Controller manufactured using an advanced 2пЃ­m
CMOS process. The 82C59A is designed to relieve the
system 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
microprocessors such as 80C286, 80286, 80C86/88,
8086/88, 8080/85 and NSC800. Features The 82C59A can handle up to eight vectored priority
interrupting 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. 80C86/88/286 and 8080/85/86/88/286 Compatible 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. Fully Static Design Pb-Free Plus Anneal Available (RoHS Compliant) 12.5MHz, 8MHz and 5MHz Versions Available High Speed, “No Wait-State” Operation with 12.5MHz
80C286 and 8MHz 80C86/88 Pin Compatible with NMOS 8259A Eight-Level Priority Controller, Expandable to
64 Levels Programmable Interrupt Modes Individual Request Mask Capability Fully TTL Compatible Low Power Operation
