Procurement Notes

Verify the obsolete status of this component through official Renesas channels before integration planning. Confirm availability of alternative packaging options such as tape and reel variants if tray quantities are unsuitable. Ensure compliance with current environmental regulations and check for any specific handling requirements associated with the FCBGA package type during procurement.

Selection Notes

Select this part when a 48-lane, 12-port PCIe Gen2 solution is required for deterministic switching. Consider the 676-FCBGA footprint constraints and industrial temperature range suitability. Evaluate partitionable architecture needs for multi-root configurations. Verify power supply compatibility with the specified 3.3V requirement and ensure PCB layout supports the 27x27 mm package dimensions.

Part Context
