Memory IC Procurement Notes

This component is officially classified as obsolete by the manufacturer. Procurement must rely on secondary market distributors or remaining stock. Verify lot dates and authenticity carefully due to end-of-life status. Export restrictions may apply depending on the destination country. Confirm RoHS compliance details directly with the seller, as legacy parts often have specific regulatory statuses.

Memory IC Selection Notes

Select this part only if the design requires a 32K x 8 organization with through-hole CDIP-28 packaging. Ensure the system can accommodate the 55 ns access speed and 125 mA current draw. Compare against newer surface-mount alternatives if space constraints exist. Verify that the 4.5 V to 5.5 V supply range matches the target power architecture without requiring level shifting.

Memory IC Part Context

This SRAM belongs to the Renesas 5962-88552 series, which focuses on high-reliability memory solutions. These components are typically utilized in applications where long-term availability and performance stability are critical. The 5962 prefix indicates a military-grade or high-reliability variant managed under specific procurement channels.

Memory IC Replacement Considerations

The datasheet lists the 5962-8855202XA as a related variant within the same family. Both share similar memory organizations but differ in access times. Verify pin compatibility and electrical specifications before substituting.
