5962-89571022A

Overview

The Broadcom Limited 5962-89571022A is a high-performance, radiation-hardened static random-access memory (SRAM) device. It features a capacity of 32 kilobits organized as 4K words by 8 bits. The component operates with a single +5V power supply and supports read/write access times of 55 nanoseconds. Designed for military and aerospace applications, it meets MIL-STD-883 standards for radiation tolerance, including total ionizing dose and single-event upset immunity.

Feature Summary

• Radiation-hardened design suitable for harsh space environments
• High-speed static RAM operation with fast access times
• Single +5V power supply compatibility
• Compliance with MIL-STD-883 military testing standards

Applications

• Military satellite communication systems
• Avionics data storage in fighter aircraft
• Spacecraft onboard computer memory modules
• Nuclear instrumentation control systems

Procurement Notes

Verify the specific grade suffix and lot traceability documentation upon receipt. Ensure that the supplier provides valid MIL-STD-883 test reports confirming radiation hardness levels. Check for proper ESD handling procedures during installation to maintain device integrity.

Selection Notes

Select this component when radiation tolerance is critical for mission reliability. Consider the 55ns access speed against system clock requirements. Evaluate the 4Kx8 organization against available board space and pin count constraints compared to alternative SRAM families.

Part Context

This part belongs to Broadcom's radiation-hardened semiconductor portfolio, specifically targeting defense and aerospace markets. It is manufactured under strict quality controls to ensure long-term stability in vacuum and high-radiation conditions, distinguishing it from commercial-grade SRAMs.

Replacement Considerations

Direct replacements include other MIL-STD-883 qualified 32Kb SRAMs such as the 5962-89571021A or equivalent parts from Texas Instruments like the TMS44C102RHQ if form-fit-function compatibility is confirmed through detailed datasheet comparison.
