Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may exist between PFI8 and PF designations. Confirm RoHS compliance status, as historical data indicates non-compliance for similar variants. Check current availability as the product line may be subject to discontinuation notices. Ensure the specific package dimensions match the 80-TQFP requirement for PCB layout.

Memory IC Selection Notes

Select this component when a 64Kb parallel SRAM with 25ns speed is required for 5V logic environments. Consider the 80-pin TQFP footprint for board space constraints. Evaluate thermal performance within the 0°C to 70°C operating range. Compare against newer low-voltage alternatives if power efficiency is a primary design driver.
