89H32NT8AG2ZAHL

Overview

The 89H32NT8AG2ZAHL is a PCI Express system interconnect switch manufactured by Renesas Electronics Corporation. It provides 32 PCIe Gen2 lanes and supports 8 switch ports, delivering high-performance, deterministic switching for multiple traffic flows. The device features a non-blocking architecture optimized for maximum bandwidth and large payloads, with internal buffering and flow control credits to ensure low latency. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 484-FCBGA package measuring 23x23 mm. Power supply requirements include 1V, 2.5V, and 3.3V rails.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Supports partitionable switch architecture for true multi-root functionality
• Includes onboard DMA support and movable upstream capabilities
• Provides internal buffering and flow control credits for large payload optimization

Applications

• High-performance server system interconnects
• Storage area network (SAN) infrastructure
• Industrial computing systems requiring multi-root support

Procurement Notes

Verify the specific suffix ZAHL against official Renesas documentation to confirm lead-free status and packaging type. Confirm current product lifecycle status as this component series may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and power delivery networks before procurement.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 applications. Consider variants with different port counts or lane configurations if system topology differs. Verify thermal management requirements due to the dense FCBGA package and high-speed signaling characteristics inherent to PCIe switches.

Part Context

This component belongs to the 89H32NT family of PCIe switches from Renesas. It shares architectural similarities with models like the 89H32NT8AG2ZBHLG8 but differs in specific suffix designations that may indicate package variations or environmental ratings. It serves as a critical node in expanding PCIe connectivity in complex electronic systems.

Replacement Considerations

Direct substitutes within the same family include 89H32NT8AG2ZBHLG8 and 89H32NT8AG2ZCHLG8. Verify pin-to-pin compatibility and electrical specifications before substitution. Other models in the 89H series may offer different port densities.
