Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package dimensions against PCB footprint specifications before procurement. Check for available upgrade alternatives from the manufacturer if long-term supply stability is required.

Memory IC Selection Notes

Select this component for designs requiring independent dual-port access without external arbitration logic. Ensure system voltage levels align with the 4.5V to 5.5V operating range. Consider the 64-TQFP package constraints during layout planning. Evaluate thermal performance within the specified commercial temperature range for reliable operation.

Memory IC Part Context

This part belongs to the 71421 series of dual-port SRAMs. It functions primarily as a slave device in 16-bit or wider systems when paired with compatible master controllers. The series is engineered for full-speed error-free operation without additional discrete logic components.
