Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by the manufacturer. Availability is restricted to remaining stock from authorized distributors or secondary market sources. Verify RoHS compliance status, as older production runs may not meet current environmental regulations. Confirm package authenticity and check for moisture sensitivity level handling requirements during procurement and storage.

Memory IC Selection Notes

Select this part only if legacy compatibility with the 71V3556 family is required. Ensure the design accommodates the specific 119-PBGA footprint and thermal characteristics. Consider that the discontinuation limits long-term supply chain stability. Evaluate alternative synchronous SRAMs with similar organization and speed grades if future production support is necessary.

Memory IC Part Context

The 71V3556 series represents a line of synchronous zero wait state SRAMs designed for applications demanding rapid data retrieval. This specific model belongs to the SA variant family, optimized for 3.3V I/O operations. It serves as a critical memory solution in systems where deterministic access times are essential for processor efficiency and system responsiveness.

Memory IC Replacement Considerations

Official substitutes include other variants within the 71V3556SA series such as the 71V3556SA166BQGI8 for higher speed requirements. Cross-reference pinouts and electrical specifications carefully when considering non-Renesas alternatives to ensure functional compatibility.
