5962-8953402MXA

Overview

The Altera 5962-8953402MXA is a math coprocessor integrated circuit belonging to the i387 series. It is designed for through-hole mounting in a 68-contact Ceramic Pin Grid Array (CPGA) package with dimensions of 29.97x29.97 mm. The component functions as a specialized IC for mathematical operations, packaged in bulk quantities. This specific part number represents a military-grade or high-reliability variant of the standard i387 architecture, adapted for integration into systems requiring robust floating-point processing capabilities within a legacy or specialized embedded environment.

Feature Summary

• Integrated math coprocessor functionality based on the i387 architecture
• 68-contact CPGA package suitable for through-hole mounting
• High-reliability construction indicated by the 5962 prefix

Applications

• Embedded systems requiring dedicated hardware floating-point acceleration
• Industrial control applications utilizing legacy processor architectures
• Military or aerospace electronic assemblies demanding high reliability

Procurement Notes

Verify the exact revision level and date code upon order confirmation, as components with the 5962 prefix often denote specific military or aerospace qualification standards. Ensure that the 68-CPGA footprint matches the target PCB design, noting the 29.97x29.97 mm body size. Confirm handling requirements for ceramic packages to prevent mechanical stress during assembly.

Selection Notes

Select this component when a system requires an external math coprocessor compatible with the i387 instruction set extension. The 68-CPGA package is necessary for applications where through-hole technology is mandated for mechanical stability or thermal management. Compare pin compatibility with existing board layouts before substitution, as package dimensions are fixed at 29.97x29.97 mm.

Part Context

This part falls under the broader category of specialized ICs, specifically math coprocessors. The 'i387' series designation links it to historical x87 floating-point unit designs. The '5962' prefix typically indicates a defense-standard version of a commercial component, ensuring stricter quality control and traceability compared to standard commercial equivalents.

Replacement Considerations

Direct replacements must match the 68-CPGA form factor and i387 functional interface. Verify electrical compatibility with the host processor's data bus and control signals. Cross-reference with other 5962-series variants if available, ensuring no functional deviations in arithmetic precision or timing.
