Memory IC Procurement Notes

This component has been officially declared obsolete and is no longer in production. Verification of availability requires checking authorized distributors for remaining stock or approved replacement parts. Buyers must confirm the specific suffix codes match their design requirements, as legacy inventory may vary in packaging or revision status. Ensure compliance with current environmental regulations when sourcing end-of-life components.

Memory IC Selection Notes

Engineers should evaluate the 7007L20PFI for designs requiring 256Kb dual-port SRAM with 20ns speed. Consider the 80-TQFP footprint constraints and 5V logic compatibility. Verify that the asynchronous interface aligns with the system bus architecture. Review the official datasheet for pinout definitions and electrical characteristics to ensure seamless integration into existing hardware platforms.

Memory IC Part Context

The 7007L20PFI belongs to the Renesas 7007 series of dual-port SRAMs, which are widely used in applications demanding high bandwidth and low latency. This specific model represents the 20ns speed grade within the 256Kb capacity segment. The series is known for its compatibility with standard microprocessor interfaces and its ability to facilitate efficient data sharing between two independent processors or controllers.

Memory IC Replacement Considerations

The official upgrade substitute is the 7007L20PFGI. This replacement maintains functional compatibility while addressing regulatory updates. Engineers should verify pin-to-pin equivalence and review any changes in environmental compliance documentation before implementing the substitution.
