• Provides four dedicated external interrupt input lines for system event handling.

Applications

• High-performance embedded control systems
• Industrial automation controllers
• Military and aerospace avionics subsystems

Procurement Notes

Verify the specific manufacturer source, as this part is associated with both Intel and Altera histories. Confirm the package type matches the required CPGA132 ceramic specification. Check RoHS compliance status, as older variants may not meet current environmental standards. Ensure the voltage levels are compatible with the target system design before procurement.

Selection Notes

Select this processor when a 32-bit RISC core with floating-point capabilities is required. Consider the wide industrial temperature range (-55 °C to 125 °C) for harsh environment deployments. Evaluate the CPGA132 ceramic package constraints against available board space and thermal management solutions. Compare performance needs against other i960 variants if different clock speeds or packages are acceptable.

Part Context

This component belongs to the i960 microprocessor family, originally developed by Intel and later supported by Altera. The i960 series was widely used in networking, storage, and industrial applications during the 1990s and early 2000s. The MG80960MC-20 represents a specific variant within this lineage, characterized by its ceramic packaging and extended temperature rating suitable for rugged environments.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official replacement guides for the i960 family or consider modern FPGA-based implementations for new designs.
