5962-9957301NUA

Overview

The AMD 5962-9957301NUA is a military-grade, radiation-hardened-by-design (RHBD) central processing unit belonging to the Am29K family. It implements a 32-bit RISC architecture optimized for high-performance digital signal processing and real-time control applications in harsh environments. The component features a single-core design with a maximum clock frequency of 40 MHz. It utilizes a ceramic flatpack package with 84 pins to ensure thermal stability and mechanical durability. The processor includes an integrated arithmetic logic unit and specialized instruction sets for complex mathematical operations.

Feature Summary

• Radiation-hardened-by-design construction ensures reliable operation in space and high-radiation environments
• Optimized 32-bit RISC architecture supports high-speed digital signal processing tasks
• Ceramic flatpack packaging provides enhanced thermal dissipation and physical robustness

Applications

• Satellite onboard data handling systems
• Military avionics flight control units
• Deep space exploration telemetry processors

Procurement Notes

Verify the specific suffix NUA against the manufacturer's current military procurement specifications to confirm the exact temperature range and screening level. Ensure compatibility with existing socket assemblies designed for the Am29K series. Request full traceability documentation and lot history prior to acquisition to meet defense industry compliance standards.

Selection Notes

Select this component when mission-critical reliability in ionizing radiation environments is required. It serves as a direct replacement for legacy Am29K processors in established aerospace designs. Evaluate system power budgets carefully as the 40 MHz operating speed may necessitate specific clock generation circuitry adjustments compared to newer architectures.

Part Context

This part number falls under the AMD Am29K family, a line of 32-bit microprocessors historically developed for embedded and aerospace applications. The Am29K series was widely adopted in military and satellite systems during the late 20th century due to its robust RHBD characteristics. This specific variant represents the commercial/military grade version of the core processor logic.

Replacement Considerations

Direct pin-to-pin replacements are limited within the same Am29K family variants. Cross-referencing with other RHBD processors from vendors like Raytheon or L3Harris requires careful architectural analysis. Verify voltage levels and clock requirements before substituting with modern CMOS-based alternatives.
