Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability requires checking authorized distributors for remaining stock or obsolete inventory. Sourcing should prioritize verified surplus suppliers. Designers must confirm RoHS compliance status, which may be non-compliant for this legacy part. Replacement strategies should focus on qualified substitute components listed in official documentation.

Selection Notes

Select this component only if legacy compatibility with the 7201L series is required. Verify that the 20 ns access time meets system timing requirements. Ensure the design accommodates the 32-PLCC surface mount package dimensions. Confirm power supply stability within the 4.5 V to 5.5 V range. Consider end-of-life implications for long-term production viability.
