Memory IC Procurement Notes

Verify the exact suffix against official Renesas documentation to confirm pinout compatibility and temperature grade. Confirm RoHS compliance status as manufacturing processes evolve. Check for active obsolescence notices or last-time-buy notifications before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 256K x 18 organization is required for synchronous memory applications. Ensure the design accommodates the specific 3.3V core voltage requirements and the physical dimensions of the 165-CABGA package. Validate thermal management strategies for the intended operating temperature range.

Memory IC Part Context

This part belongs to the IDT 71V3559 family of synchronous SRAMs, now manufactured under the Renesas Electronics brand following corporate acquisitions. The series is characterized by its zero-burst architecture, which maintains constant throughput regardless of address patterns, making it suitable for pipeline-based system designs.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Consider variants such as the 71V3559S80BG8 for different packaging options, ensuring functional equivalence in speed and organization.
