• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Supports partitionable switch architecture for true multi-root functionality
• Includes multiple Nontransparent Bridging (NTB) functions and movable upstream support
• Features internal buffering and flow control credits optimized for maximum bandwidth

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial temperature grade applications

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or alternative packaging types. Compliance status varies by suffix; some variants are RoHS compliant while others are not. Confirm moisture sensitivity level and specific environmental certifications before procurement planning.

Selection Notes

Select this part for designs requiring 16-lane PCIe Gen2 connectivity within a compact FCBGA footprint. Ensure the design accommodates the 324-ball package dimensions and pitch. Verify thermal requirements for the operating temperature range. Consider that the product lifecycle is end-of-life, necessitating long-term supply chain risk assessment for production volumes.

Part Context

The 89H16NT16G2ZAHLI8 belongs to the 89HPES16NT16G2 family of PCI Express switches from IDT, now part of Renesas. This family includes various pinout and packaging options such as ZAHL8, ZCHLGI8, and ZBHLI8. These devices share core switching capabilities but differ in package type, lead-free status, and commercial/industrial temperature ratings.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the device is obsolete, engineers must evaluate newer generations of PCIe switches from Renesas or other manufacturers that offer compatible lane counts and port configurations.
