• Includes multiple nontransparent bridging (NTB) functions and movable upstream support

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• PCIe I/O expansion systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Availability is restricted or limited, often requiring factory special orders or existing stock from authorized distributors. Verification of RoHS compliance status is required as it may not meet current environmental standards. Engineers should confirm lead times and authenticity carefully due to the end-of-life status.

Selection Notes

Designers should evaluate alternative components from the same family or newer generations due to the obsolete status of this part. Considerations must include pin compatibility, package dimensions, and electrical specifications such as voltage levels and lane counts. Migration strategies should account for potential differences in feature sets and software support between legacy and current switch ICs.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe Gen2 switches. It shares architectural similarities with other variants like the 89H24NT6AG2 but offers higher port density. The suffix indicates specific packaging and material configurations. It is designed for deterministic switching applications requiring low latency and internal buffering.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Renesas technical resources for current product recommendations replacing obsolete PCIe switch devices.
