Overview
The MD8087/R is a math coprocessor manufactured by Rochester Electronics, LLC. It is designed for 16-bit processing tasks and utilizes HMOS technology. The component is housed in a CDIP40 package, providing 40 connection pins. This device serves as a peripheral to microprocessors, handling complex mathematical operations to offload the central processing unit.
Feature Summary
- Executes 16-bit mathematical calculations
- Utilizes HMOS semiconductor technology
- Provides dedicated arithmetic processing support
Applications
- Legacy computer system maintenance
- Industrial control systems requiring floating-point acceleration
- Obsolete hardware restoration projects
Procurement Notes
Verify the specific suffix designation with the manufacturer or authorized distributor to confirm exact binning and testing criteria. Ensure compatibility with existing motherboard architectures before procurement. Request detailed lot traceability documentation to validate authenticity and storage history. Confirm that the CDIP40 pin configuration matches the target socket requirements without modification.
Selection Notes
Select this component when replacing obsolete Intel 8087-series units in legacy designs. Verify that the host processor supports the required instruction set extensions. Consider the physical dimensions of the CDIP40 package during PCB layout review. Ensure thermal management strategies align with HMOS power dissipation characteristics for long-term reliability.
Part Context
Rochester Electronics specializes in continuing supply solutions for end-of-life semiconductors. The MD8087/R represents their offering of historically significant math coprocessors. This part maintains functionality for systems no longer supported by original equipment manufacturers. It bridges the gap between legacy hardware requirements and modern supply chain constraints.
Replacement Considerations
Direct substitutes include other 8087-compatible math coprocessors in CDIP40 packages. Verify electrical compatibility with the host CPU before installation. Check for any necessary firmware updates to ensure proper handshake protocols.
