Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

PROGRAMMABLE INTERRUPT CONTROLLER
This product is not available in Asia and Oceania.
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 100
mA
(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.
FEATURES
• Silicon gate CMOS technology for high speed and low power consumption
• 3 V to 6 V single power supply
• MSM80C85AH system compatibility (MAX. 5 MHz)
• MSM80C86A-10/88A-10 system compatibility (MAX. 8 MHz)
• 8-level priority interrupt control
• Interrupt levels expandable up to 64 levels
• Programmable interrupt mode
• Maskable interrupt
• Automatically generated CALL code (85 mode)
• TTL compatible
• 28-pin Plastic DIP (DIP28-P-600-2.54): (Product name: MSM82C59A-2RS)
• 28-pin Plastic QFJ (QFJ28-P-S450-1.27): (Product name: MSM82C59A-2JS)
• 32-pin Plastic SSOP (SSOP32-P-430-1.00-K): (Product name: MSM82C59A-2GS-K)
