89H32NT8BG2ZAHL

Overview

The 89H32NT8BG2ZAHL is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as a PCI Express switch. It provides 32 PCIe Gen2 lanes and supports 8 ports for high-performance system interconnect switching. The device features a non-blocking architecture optimized for deterministic throughput across multiple traffic flows. It operates with supply voltages of 1 V, 2.5 V, and 3.3 V. The component is housed in a 484-FCBGA package measuring 23x23 mm. It supports surface mount installation and is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput regardless of switch loading
• Partitionable switch design enabling true multi-root support capabilities
• Support for multiple Nontransparent Bridging (NTB) functions
• Internal buffering and flow control credits optimized for large payloads

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Industrial data acquisition systems

Procurement Notes

Verify the specific suffix requirements for lead-free status and packaging type when sourcing this component. Confirm RoHS compliance details as some variants may differ. Check current availability status as older generation switches may have limited stock or end-of-life implications. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 applications. Consider the 484-FCBGA package size constraints during layout. Evaluate power supply requirements for the 1V, 2.5V, and 3.3V rails. Compare against newer generations if higher bandwidth or lower latency is needed for future-proofing designs.

Part Context

This part belongs to the Renesas 89H series of PCIe switches, specifically the NT8 variant indicating 8 ports. It succeeds earlier PES series models and offers enhanced lane counts compared to smaller port configurations. The G2 designation confirms PCIe Generation 2 support. It is part of Renesas' legacy portfolio acquired through IDT integration.

Replacement Considerations

Direct pin-to-pin replacements are not publicly confirmed for this specific suffix combination. Review the 89H32NT8AG2ZCHLG8 for potential functional equivalents within the same family. Verify electrical compatibility and firmware requirements before substituting with other 8-port PCIe switches.
