89H24NT6AG2ZCHL

Overview

The Renesas 89H24NT6AG2ZCHL is a PCIe Gen2 system interconnect switch providing 24 lanes and 6 ports. It delivers 192 Gbps of non-blocking throughput with full line rate performance across all ports. The device supports x4, x2, and x1 link widths with automatic negotiation. It features partitionable architecture for multi-root support and includes Non-Transparent Bridging (NTB) functions. Operating temperatures range from -40°C to +85°C. The component utilizes a 484-pin FCBGA package measuring 23x23 mm.

Feature Summary

• Partitionable switch architecture enabling true multi-root support through dynamic reconfiguration of downstream, upstream, and non-transparent bridge ports.
• Integrated Non-Transparent Bridging (NTB) capabilities allowing communication between switch partitions, external PCIe domains, or CPUs.
• Low latency, low power design optimized for high-performance system interconnects with internal buffering and flow control credits.

Applications

• Multi-host or intelligent I/O systems requiring cross-domain communication
• Server infrastructure demanding deterministic system interconnect switching
• Storage area networks and embedded systems needing peer-to-peer data transfers

Procurement Notes

Verify the specific suffix ZCHL against current manufacturer documentation to confirm lead-free status and industrial temperature grade. Confirm availability as this part number may be obsolete or discontinued. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Selection Notes

Select this component when 24 lanes of PCIe Gen2 bandwidth are required in a compact form factor. Consider the partitionable architecture if logical isolation between multiple hosts is necessary. Verify that the 484-pin FCBGA package fits within the board layout constraints and that the industrial temperature range meets environmental specifications.

Part Context

This device belongs to the IDT 89HPES series of PCIe switches, now under Renesas Electronics. It is designed for high-performance computing environments where deterministic switching and low latency are critical. The series supports both root complex and endpoint configurations within a single integrated circuit.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Check manufacturer discontinuation notices for potential end-of-life replacements or next-generation equivalents within the same product family.
