89H24NT6AG2ZBHLI8

Overview

The 89H24NT6AG2ZBHLI8 is a specialized PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It provides 24 PCIe Gen2 lanes and 6 switch ports, delivering high-performance, deterministic system interconnect switching with non-blocking throughput for multiple traffic flows. The device operates on a 3.3V supply voltage and utilizes a 484-FCBGA package measuring 23x23 mm. It supports industrial temperature ranges and includes features such as onboard DMA, internal buffering, and flow control credits optimized for maximum bandwidth.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports true multi-root configurations through partitionable switch architecture
• Enables movable upstream support and multiple Nontransparent Bridging (NTB) functions
• Integrates onboard DMA and internal buffering to optimize bandwidth for large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures requiring partitionable switches
• PCIe Gen2 expansion systems demanding low latency and high throughput

Procurement Notes

Verify component authenticity and condition upon receipt, as this part is listed as obsolete. Check for moisture sensitivity level 4 compliance if storage conditions were not strictly controlled. Confirm the specific suffix ZBHLI8 matches design requirements, noting that packaging variations exist within the family. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before integration into new or replacement designs.

Selection Notes

Select this component when designing systems requiring 24 lanes of PCIe Gen2 connectivity across six distinct ports. It is suitable for applications needing deterministic switching performance and non-blocking data transfer capabilities. Consider the 484-FCBGA form factor for board space constraints. Evaluate power consumption profiles against system thermal limits, as the device supports low-latency operation while maintaining efficient power usage under varying load conditions.

Part Context

This device belongs to the 89H24NT6AG2 series of PCIe switches from Renesas. It shares architectural similarities with other models in the family, such as the 89H32NT24AG2, but offers a specific configuration of 24 lanes and 6 ports. The product line is designed for robust system interconnect solutions, often replacing legacy switching technologies in modern high-speed computing environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the component is marked obsolete, engineers should consult Renesas technical support for current alternatives or evaluate pin-compatible devices from other manufacturers after verifying electrical and functional specifications.
