89H24NT6AG2ZAHLI8

Overview

The 89H24NT6AG2ZAHLI8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 6 ports of high-performance, deterministic switching. The device features a non-blocking architecture optimized for multi-root support and includes partitionable switch capabilities. It supports Non-Transparent Bridging (NTB) functions and movable upstream ports. The component is housed in a 484-pin FCBGA package with dimensions of 23x23 mm. Operating voltage levels include 1V, 2.5V, and 3.3V. The industrial temperature grade ranges from -40°C to +85°C.

Feature Summary

• Partitionable switch architecture enabling true multi-root support through up to six independent logical partitions.
• Support for multiple Non-Transparent Bridging (NTB) functions allowing communication between switch partitions and external domains.
• Movable upstream port capability providing flexible topology configuration within the switch partitions.

Applications

• High-performance server system interconnects requiring multi-root I/O virtualization.
• Storage area networks needing deterministic bandwidth allocation.
• Communication infrastructure equipment utilizing partitioned data paths.

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm moisture sensitivity level handling requirements prior to assembly. Ensure compatibility with existing PCB footprints for the 484-FCBGA package. Review latest Product Change Notices for any material or packaging updates issued by the manufacturer.

Selection Notes

Select this model when designing systems requiring 24 PCIe Gen2 lanes with flexible partitioning. Compare against the 89HPES24T6G2ZCALI8 if Gen1 speeds are sufficient and a smaller 324-pin package is preferred. Evaluate the 89H32NT24AG2 for applications demanding higher lane counts. Ensure design supports the specific voltage rails required for core and I/O operations.

Part Context

This component belongs to the IDT/Renesas 89H24NT6AG2 series of PCIe switches. It is designed for high-throughput environments where low latency and non-blocking performance are critical. The series supports advanced features like on-board DMA and internal buffering to maximize bandwidth utilization for large payloads.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider evaluating the 89HPES24T6G2ZCALI8 for Gen1 compatibility or the 89H32NT24AG2 for increased capacity, pending verification of pinout and feature parity.
