Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as specifications may vary by revision. Check moisture sensitivity level handling procedures before assembly. Validate package dimensions against PCB footprint designs. Ensure supply chain stability given discontinued manufacturing status.
Selection Notes
Select this part for applications needing wide word width (36-bit) synchronous memory. Compare access times and power consumption against alternative ZBT SRAMs. Consider the 165-CABGA package constraints during layout. Verify voltage compatibility with system I/O levels. Assess thermal performance within the specified operating range.
Part Context
This component belongs to the 71V3556 series of synchronous SRAMs from Renesas. It shares architectural similarities with other members like the 71V3556SA100BQ8 but differs in packaging and temperature rating. The series is designed for high-speed data buffering and caching in complex digital systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for direct replacements or pin-compatible alternatives.
