E2O0021-27-X3 ¡ Semiconductor MSM82C59A-2RS/GS/JS ¡ Semiconductor PROGRAMMABLE INTERRUPT CONTROLLER This version: Jan. 1998 MSM82C59A-2RS/GS/JS Previous version: Aug. 1996 GENERAL DESCRIPTION The MSM82C59A-2 is a programmable interrupt for use in MSM80C85AH and MSM80C86A10/88A-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. FEATURES Silicon gate CMOS technology for high speed and low power consumption 3 V to 6 V single power supply MSM80C85AH system compatibility (MAX5 MHz) MSM80C86A-10/88A-10 system compatibility (MAX8 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) www.DataSheet4U.com 32-pin Plastic SSOP (SSOP32-P-430-1.00-K): (Product name: MSM82C59A-2GS-K) Free Datasheet http://www.datasheet4u.com/ 1/28 ¡ Semiconductor MSM82C59A-2RS/GS/JS BLOCK DIAGRAM INTA INT D7 - D0 Data Bus Buffer C...
