89H24NT6AG2ZAHLGI

Overview

The Renesas 89H24NT6AG2ZAHLGI is a discontinued PCI Express Gen2 system interconnect switch providing 24 lanes and 6 ports. It features a non-blocking architecture with full line-rate throughput for multiple traffic flows. The device supports partitionable switching for multi-root configurations and includes Non-Transparent Bridging (NTB) functions. It operates on 3.3V power and utilizes an FCBGA package with 484 leads, measuring 23x23 mm. The component is designed for high-performance server, storage, and communication applications requiring deterministic low-latency data exchange.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnects
• Partitionable switch design enabling true multi-root support across six independent zones
• Integrated Non-Transparent Bridging (NTB) functions for secure domain isolation
• Support for movable upstream ports and dynamic port reconfiguration

Applications

• High-performance server system interconnects
• Storage area network controllers
• Communication infrastructure equipment
• Multi-host intelligent I/O systems

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or secondary market sources. Ensure compatibility with existing PCB footprints and validate that alternative components meet the required PCIe Gen2 electrical specifications before integration.

Selection Notes

Select this part for designs requiring 24 lanes of PCIe Gen2 connectivity with flexible port configuration. Verify that the application benefits from its specific NTB capabilities and partitioning features. Consider pinout compatibility if migrating from previous IDT generations. Confirm that the 484-FCBGA package constraints fit the target board layout.

Part Context

This device belongs to the 89HPES24NT6AG2 family of PCIe switches. It shares core architectural features with variants like the 89H24NT6AG2ZCHLGI but may differ in lead-free status or temperature grade suffixes. The 'ZA' suffix typically indicates specific manufacturing or material compliance attributes within the Renesas portfolio.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Engineers should evaluate other members of the 89HPES24NT6AG2 series or newer PCIe Gen3/Gen4 switches from Renesas, ensuring functional equivalence in lane count and NTB support.
