Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm exact speed grade and package variant. Confirm RoHS compliance status as indicated in the datasheet, noting that military-grade variants may have different regulatory classifications. Ensure the procurement channel provides traceability documentation required for defense or aerospace applications. Check for end-of-life notices or obsolescence warnings prior to finalizing orders.

Memory IC Selection Notes

Select this component when design requirements demand high-temperature operation beyond standard commercial limits. The CDIP package is appropriate for applications prioritizing mechanical strength over board space efficiency. Verify that the 5V logic levels align with the host system's I/O specifications. Consider the 70 ns access time relative to the processor clock speed to ensure adequate timing margins for the target application architecture.

Memory IC Part Context

This part belongs to the Renesas 5962-88552 series, which comprises radiation-hardened and high-reliability SRAM devices. These components are typically utilized in sectors where standard commercial parts fail due to environmental stress. The series offers various density and speed options within the same form factor, allowing for design flexibility while maintaining consistent packaging and pinout characteristics across the family.

Memory IC Replacement Considerations

Direct replacements must match the 28-CDIP package, 32Kx8 organization, and 70 ns minimum speed. Verify that any substitute maintains the same voltage and temperature specifications. Cross-reference with other manufacturers offering MIL-SPEC equivalent SRAMs if Renesas availability is restricted.
