Procurement Notes

Verify the current manufacturing status before procurement, as this specific part number may be obsolete or subject to end-of-life notices. Confirm that the 100-TQFP package dimensions match your PCB footprint requirements. Ensure that the 3.3V I/O voltage levels are compatible with your system's logic family. Check for moisture sensitivity level (MSL) handling requirements during storage and assembly processes to prevent damage.

Selection Notes

Select this component when a 36-bit data width is required for synchronous memory operations. Consider the 8 ns access time for timing constraints within your design. Evaluate the 100-pin TQFP package size against available board space. Compare power consumption specifications against thermal management capabilities if operating at maximum clock frequencies. Verify compatibility with existing controller interfaces supporting synchronous SRAM protocols.

Part Context

This component belongs to the 71V547 series of synchronous SRAM devices from Renesas Electronics. The series typically offers various speed grades and organization options for different performance requirements. The 71V547S80PFGI8 specifically targets applications needing moderate speed with wide data paths. It represents a legacy product line often used in established industrial and communication designs where pin compatibility is critical.

Replacement Considerations

The 71V547S100PFGI8 is listed as a similar replacement option. Verify that the increased access time does not violate system timing requirements. Ensure electrical characteristics remain compatible with the original design specifications.
