89H32NT8AG2ZAHLI

Overview

The 89H32NT8AG2ZAHLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic switching with non-blocking architecture. The device supports full line rate throughput for multiple traffic flows regardless of switch loading. It features a partitionable architecture for multi-root support, movable upstream capabilities, and onboard DMA. Power supply voltages include 1 V, 2.5 V, and 3.3 V. The component operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging (NTB) functions
• Onboard DMA support with internal buffering and flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks requiring deterministic latency

Procurement Notes

Verify the specific suffix ZAHLI against official Renesas documentation to confirm lead-free status and packaging type. Cross-reference the part number with current product change notices as legacy PCIe switches may have limited availability or obsolescence statuses. Ensure compatibility with existing board designs regarding voltage levels and thermal requirements before procurement.

Selection Notes

Select this component when 32 lanes and 8 ports are required for PCIe Gen2 systems. Consider the 484-FCBGA package size for PCB layout constraints. Evaluate power consumption profiles across the 1 V, 2.5 V, and 3.3 V rails. Confirm that the industrial temperature range meets environmental specifications. Compare against newer generation switches if higher data rates are needed.

Part Context

This part belongs to the 89H32NT series of PCIe switches from Renesas, formerly IDT. It is designed for scalable system interconnects. Related variants include different port counts such as the 89H32NT24AG2. The series emphasizes low latency and high bandwidth for enterprise and computing applications.

Replacement Considerations

Check for direct pin-to-pin replacements in the same family. Newer generations like PCIe Gen3 or Gen4 switches may require signal integrity redesigns. Verify if updated suffixes indicate RoHS compliance changes.
