Overview
The MG80387-25/R is a math coprocessor manufactured by Rochester Electronics, LLC. It is designed to function as a peripheral for microprocessor systems, providing enhanced floating-point and integer arithmetic capabilities. The device operates at a clock speed of 25 MHz, indicated by the suffix '25'. It is housed in a 68-pin Plastic Grid Array (PGA) package, configured for tube packaging. This component serves as a specialized accelerator for computational tasks within embedded or industrial control architectures.
Feature Summary
- Provides dedicated mathematical processing acceleration for system microprocessors
- Operates with a fixed 25 MHz clock frequency specification
- Utilizes a 68-pin PGA interface for board integration
Applications
- Industrial control systems requiring high-speed arithmetic
- Embedded computing platforms needing floating-point support
- Legacy microprocessor peripheral expansion
Procurement Notes
Verify the specific lot date code and manufacturing origin when ordering from authorized distributors like Rochester Electronics. Confirm that the 68-PGA tube packaging matches your handling equipment. Ensure compatibility with the host microprocessor architecture before procurement, as this is a specialized peripheral component rather than a general-purpose processor.
Selection Notes
Select this component when the primary CPU lacks sufficient hardware-based mathematical instruction sets. The 25 MHz speed rating must align with the system bus requirements. Consider the PGA package size and pin count during PCB layout planning. Verify that the application environment supports the thermal characteristics associated with this specific package type and operating frequency.
Part Context
Rochester Electronics specializes in the lifecycle management of obsolete and hard-to-find semiconductors. The MG80387 series represents a continuation of legacy math coprocessor designs, ensuring availability for long-term industrial and aerospace applications where original manufacturers have discontinued production. This part is part of their authorized reproduction portfolio.
Replacement Considerations
Direct functional replacements are limited due to the proprietary nature of legacy math coprocessor interfaces. Verify pinout compatibility if considering alternative math accelerators. Software migration may be required if substituting with different architectural coprocessors. Consult technical documentation for electrical parameter matching.
