Overview
The MG80960MC-25 is a 32-bit RISC microprocessor manufactured by Rochester Electronics, LLC. It operates at a clock frequency of 25 MHz and integrates a floating-point unit (FPU) and a memory management unit (MMU). The device utilizes CMOS technology and is housed in a CPGA132 package with a 2.54 mm pitch ceramic PGA construction. This component supports high-bandwidth burst bus operations and features a large register set with multiple parallel execution units for efficient processing.
Feature Summary
- Integrates a dedicated floating-point unit for complex mathematical computations
- Includes an on-chip memory management unit for address translation
- Features a large register set to reduce memory access latency
- Supports multiple parallel execution units for instruction throughput
Applications
- Industrial control systems requiring real-time processing
- Embedded applications needing hardware memory management
- Legacy system maintenance and replacement
- Scientific instrumentation with floating-point requirements
Procurement Notes
Verify the specific suffix designation, such as /B, against your bill of materials, as it may indicate variations in lot date codes or minor manufacturing revisions. Confirm that the CPGA132 ceramic package dimensions match your existing PCB footprint. Ensure compatibility with the target operating voltage and signal levels before integration into the final assembly.
Selection Notes
Select this component when a 32-bit RISC architecture with integrated FPU and MMU is required for legacy compatibility. The 25 MHz speed rating suits applications where moderate processing performance is sufficient. Consider the ceramic PGA package if thermal stability and mechanical robustness are prioritized over surface-mount convenience. Verify that the pinout aligns with the original design specifications.
Part Context
This part belongs to the Intel 80960 family, specifically the MC variant, which includes the memory management unit. Rochester Electronics supplies these components as surplus or lifecycle continuation products. The MG80960MC-25 serves as a direct functional equivalent to the original Motorola/Freescale MC68020 series processors in many embedded designs.
Replacement Considerations
The MG80960MC-25/B is a verified alternative variant from the same manufacturer. Cross-reference with the MC68020CRC25E for functional compatibility in legacy systems. Ensure software binaries are compatible with the 80960 instruction set architecture before substituting.
