Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm RoHS compliance status, as specific suffixes indicate lead-free or restricted substance variations. Ensure the 119-pin BGA footprint matches the target PCB design before procurement.

Selection Notes

Select this component when a 9Mb density with 133MHz synchronous performance is required in a compact BGA form factor. Consider the 4.2ns access speed for latency-sensitive applications. Verify that the operating temperature range meets the environmental requirements of the final assembly.

Part Context

This part belongs to the 71V65803 family of synchronous SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the series but differs in pin count, package type, and specific timing characteristics defined by its suffix.

Replacement Considerations

Check for official substitute part numbers provided by Renesas Electronics. Verify pin compatibility and electrical specifications if replacing with similar SRAM devices from other manufacturers.
