89H24NT6AG2ZAHL

Overview

The 89H24NT6AG2ZAHL is a discontinued PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 6 ports of high-performance, deterministic switching with non-blocking architecture. The device supports up to 192 Gbps aggregate bandwidth and features partitionable switch architecture for multi-root support. It includes Non-Transparent Bridging (NTB) functions, movable upstream ports, and on-board DMA capabilities. The component is housed in a 484-pin FCBGA package.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnects
• Partitionable switch architecture enabling true multi-root support
• Support for multiple Non-Transparent Bridging (NTB) functions
• Movable upstream port support for flexible topology configuration

Applications

• High-performance server system interconnects
• Storage area networks requiring multi-root access
• Communication infrastructure equipment
• Embedded systems needing PCIe expansion

Procurement Notes

This specific part number is obsolete and no longer in production. Verification of availability requires checking secondary market distributors or surplus inventory providers. Ensure compatibility with existing system designs as original manufacturer support and new unit procurement are unavailable.

Selection Notes

Designers should evaluate the 89H24NT6AG2 family variants for pin-to-pin or functional compatibility if available. Consider the transition to newer PCIe generations for new designs due to the discontinuation status. Verify voltage requirements and thermal specifications against current system constraints before sourcing from third-party suppliers.

Part Context

The 89H24NT6AG2ZAHL belongs to the IDT/Renesas 89H24NT6AG2 series of PCIe switches. This series was designed to address the needs of complex I/O expansion and peer-to-peer data transfers in enterprise environments. The 'Z' suffix typically indicates lead-free compliance, while 'AHL' denotes specific packaging and temperature grade variations within the product line.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Engineers must consult Renesas technical support or authorized distributors for legacy replacement recommendations or equivalent modern PCIe switch solutions.
