Memory IC Procurement Notes

Verify the exact suffix against official documentation, as variations may indicate different temperature ranges or packaging types. Confirm RoHS compliance status, as this specific part number may not meet current environmental standards. Check for active discontinuance notices from Renesas Electronics to ensure long-term availability and support viability.

Memory IC Selection Notes

Select this component when a 16 kbit dual-port SRAM with 45 ns access speed is required. Ensure the design accommodates the 52-PLCC surface mount package. Verify that the operating environment falls within the specified commercial temperature range and that the 5V logic levels match the system requirements.

Memory IC Part Context

This part belongs to the Renesas 71321 series of dual-port SRAMs. It shares architectural similarities with other members like the 71321LA55JI but differs in access speed. The series is designed for applications requiring concurrent processor and peripheral access to shared memory resources without bus contention.

Memory IC Replacement Considerations

The IDT71321LA45JI is a confirmed substitute part number for this component. Verify pinout compatibility and electrical specifications before implementation.
