Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm pinout and electrical characteristics, as suffixes often denote package or temperature variations. Confirm RoHS compliance status directly from the manufacturer's current datasheet, as legacy listings may show conflicting regulatory information. Ensure the source document explicitly identifies this part number to avoid confusion with similar variants in the 89H32T8G2 series.

Selection Notes

Select this component when designing systems that require a dense PCIe Gen2 switch topology with 32 lanes. Evaluate the thermal performance requirements associated with the FCBGA-484 package for your specific enclosure constraints. Compare against newer Gen3 or Gen4 alternatives if future-proofing is required, noting that this device is limited to 2.5 GT/s per lane speeds.
