MSM82C59A-2RS/GS/JS
Previous version: Aug. 1996
GENERAL DESCRIPTION
The MSM82C59A-2 is a programmable interrupt for use in MSM80C85AH and MSM80C86A-
10/88A-10 microcomputer systems.
Based on CMOS silicon gate technology, this device features an extremely low standby current
of 100mA (max.) in chip non-selective status. During interrupt control status, the power
consumption is very low with only 5 mA (max.) being required.
Internally, the MSM82C59A-2 can control priority interrupts up to 8 levels, and can be
expanded up to 64 levels by cascade connection of a number of devices.
