5962-8513303QA

Overview

The Altera 5962-8513303QA is a microprocessor unit (MPU) IC based on the Intel 80287 architecture. It operates at a clock frequency of 6 MHz and features an 8-bit data bus width with 80-bit precision capabilities. The device is housed in a 40-pin Ceramic Dual In-line Package (CDIP). This component serves as a math co-processor, designed to handle complex floating-point arithmetic operations for embedded systems requiring high computational accuracy.

Feature Summary

• Implements Intel 80287 mathematical coprocessor architecture
• Provides 80-bit precision floating-point calculation support
• Operates with a maximum clock speed of 6 MHz
• Utilizes a robust 40-pin ceramic dual in-line package

Applications

• Embedded systems requiring hardware-based floating-point acceleration
• Industrial control units needing precise mathematical computations
• Legacy computing architectures utilizing the 80287 instruction set
• Scientific instrumentation with strict numerical accuracy requirements

Procurement Notes

Verify the specific suffix 'QA' indicates military or extended temperature grade specifications if required by your design. Confirm the 40-CDIP package dimensions match your PCB footprint exactly. Ensure compatibility with the host processor's address and data bus timing before integration. Request official datasheets to validate electrical characteristics against your system constraints.

Selection Notes

Select this component when an 80287-compatible math coprocessor is mandatory for legacy software compatibility. Consider the 6 MHz operational limit when designing clock circuits. The CDIP package requires specific mounting techniques compared to surface-mount alternatives. Evaluate thermal dissipation needs within the ceramic enclosure for enclosed environments.

Part Context

This part number falls under Altera's distribution of legacy semiconductor components, often sourced from original equipment manufacturers. The 5962 prefix typically denotes a military-grade or high-reliability variant of standard commercial parts. Altera acts as a distributor for these specific MPU components rather than manufacturing the silicon die itself.

Replacement Considerations

Direct substitutes include other 80287-compatible coprocessors in CDIP packages. Verify pinout compatibility and clock speed ratings before swapping. Alternative packages may require adapter solutions. Check for updated revisions that maintain functional equivalence while offering improved availability.
