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) 1/28 ¡ Semiconductor MSM82C59A-2RS/GS/JS BLOCK DIAGRAM INTA INT D7 - D0 Data Bus Buffer Control Logic RD WR A0 CS Read/ Write Logic InService Register (ISR) Priority Resolver Interrupt Request Register (IRR) IR0 IR1 IR2 IR3 IR4 IR5 IR6 IR7 CAS0 CAS1 CAS2 SP/EN Cascade Buffer/ Comparator Interrupt Mask Register (IMR) Internal Bus (8 bits) MSM82C59A-2 Internal Block Diagram www.DataSheet4U.com 2/28 ¡ Semiconductor MSM82C59A-2RS/GS/JS PIN CONFIGURATION (TOP VIEW) 32 pin Plastic SSOP 28 pin Plastic DIP CS WR RD D7 D6 D5 D4 D3 D2 D1 D0 CAS0 CAS1 GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 28 27 26 25 24 23 22 21 20 19 18 17 16 15 VCC AO INTA IR7 IR6 IR5 IR4 IR3 IR2 IR1 IR0 INT SP/EN CAS2 CS WR RD NC D7 D6 D5 D4 D3 D2 D1 D0 NC CAS0 CAS1 GND 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 32 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 VCC AO INTA NC IR7 IR6 IR5 IR4 IR3 IR2 IR1 IR0 NC INT SP/EN CAS2 28 pin Plastic QFJ 28 VCC D6 5 26 INTA 2 WR 3 RD 1 CS 27 A0 4 D7 25 IR7 24 IR6 23 IR5 22 IR4 21 IR3 20 IR2 19 IR1 GND 14 SP/EN 16 CAS0 12 CAS1 13 CAS2 15 INT 17 IR0 18 www.DataSheet4U.com D5 6 D4 7 D3 8 D2 9 D1 10 D0 11 3/28 ¡ Semiconductor MSM82C59A-2RS/GS/JS ABSOLUTE MAXIMUM RATINGS Parameter Power Supply Voltage Input Voltage Output Voltage Storage Temperature Power Dissipation Symbol VCC VIN VOUT TSTG PD Conditions Respect to GND — Ta = 25°C 0.9 Rating MSM82C59A-2RS MSM82C59A-2GS MSM82C59A-2JS Unit V V V °C 0.9 W –0.5 - +7 –0.5 - VCC +0.5 –0.5 - VCC +0.5 –55 - +150 0.7 OPERATING RANGES Parameter Power Supply voltage Operating Temperature Symbol VCC TOP Range 3-6 –40 - +85 Unit V °C RECOMMENDED .
