IS82C59A-12R2413

Specialized Overview

The IS82C59A-12R2413 is a CMOS Priority Interrupt Controller manufactured by Harris Corporation. It operates at a maximum frequency of 12.5MHz, providing high-speed, no wait-state performance. The component is housed in a 28-pin PLCC package and is designed to manage up to eight vectored priority interrupting sources. It supports cascading capabilities to handle up to 64 sources without additional circuitry. The device ensures low operating power through static CMOS design and maintains compatibility with industry-standard microprocessor formats.

Specialized Feature Summary

• Relieves system CPU from polling tasks in multilevel priority systems
• Supports individual masking and prioritization of interrupting sources
• Compatible with both 8080/85 and 80C86/88/286 operational modes
• Enables cascading to 64 sources without extra circuitry

Specialized Applications

• Multilevel priority interrupt systems
• Microprocessor-based computer architectures
• Systems requiring vectored interrupt handling

Specialized Procurement Notes

Verify the specific suffix R2413 against official Harris documentation to confirm reel packaging specifications and RoHS compliance status. Ensure the procurement source provides valid manufacturer traceability for this specialized interface controller. Cross-reference the part number with Intersil or Renesas equivalents if sourcing from alternative distributors to confirm functional equivalence.

Specialized Selection Notes

Select this component when a 12.5MHz operation speed is required for priority interrupt control. It is suitable for designs needing direct compatibility with 8086/88 and 80286 families. Consider the PLCC package form factor for surface-mount applications. Evaluate the need for cascading capabilities if more than eight interrupt sources are present in the system architecture.

Specialized Part Context

The IS82C59A-12R2413 belongs to the 82C59A family of CMOS Priority Interrupt Controllers. This series includes variants such as the IP82C59A-5 (5MHz) and standard 82C59A (8MHz). The family is characterized by advanced 2µm CMOS process technology, offering performance equal to or greater than equivalent products at lower power consumption levels compared to older NMOS implementations.

Specialized Replacement Considerations

CS82C59A-12Z (Renesas Electronics) offers similar 12.5MHz performance in a 28-LCC package. ID82C59A (Harris Semiconductor) represents a related variant within the same product line. Verify pinout and package dimensions when substituting between PLCC and LCC formats.
