FIFOs Memory Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics. Verification of current availability requires checking authorized distributors for remaining stock or surplus inventory. Ensure that any sourced units are genuine and have not exceeded moisture sensitivity limits during storage. Replacement planning should prioritize compatible alternative part numbers immediately.

FIFOs Memory Selection Notes

Select this component only if the specific 256x18 organization and 128-TQFP footprint are mandatory for the design. The synchronous interface requires careful clock domain management. Due to its obsolete status, long-term supply continuity cannot be guaranteed. Engineers should evaluate pin-compatible alternatives from the same family or newer generations to ensure project longevity.

FIFOs Memory Part Context

The 72V805L15PF belongs to the Renesas 72V series of high-performance FIFOs. This series is designed for applications requiring large buffer depths and wide data paths. The device utilizes advanced CMOS technology to achieve low power consumption while maintaining high-speed operation suitable for demanding digital systems.

FIFOs Memory Replacement Considerations

Direct substitutes include the 72V805L15PFGI. Verify pin compatibility and electrical specifications before integration.
