• Includes on-board DMA support and internal buffering with flow control credits

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure routing
• Multi-root compute node aggregation

Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires direct consultation with authorized distributors or Renesas sales channels. Buyers must confirm lead times and potential obsolescence risks before procurement planning. Alternative sourcing may involve limited stock from third-party suppliers rather than factory-direct supply.

Selection Notes

Engineers should verify compatibility with PCIe Gen2 specifications when integrating this switch into modern systems. The 484-FCBGA package requires specific PCB layout considerations for thermal management and signal integrity. Ensure that power delivery networks support the required 1 V, 2.5 V, and 3.3 V rails simultaneously. Check for RoHS compliance status if environmental regulations apply to the target deployment region.
