Specialized Procurement Notes

Verify the specific suffix AZCBCI against official Renesas documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as legacy components may have varying environmental declarations. Check for active Product Discontinuance Notices (PCN) prior to procurement decisions.

Specialized Selection Notes

Select this component when a PCIe Gen2 switch solution with specific port configurations is required. Ensure the design accommodates the CABGA-324 package dimensions and thermal requirements. Verify that the system voltage levels align with the device specifications. Consider availability constraints due to potential end-of-life status associated with older IDT/Renesas switch families.
