89H32NT8BG2ZAHL8

Overview

The 89H32NT8BG2ZAHL8 is a PCI Express system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe Gen2 lanes and supports 8 switch ports. The device operates with supply voltages of 1 V, 2.5 V, and 3.3 V. It utilizes a 484-FCBGA package with dimensions of 23x23 mm. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple nontransparent bridging (NTB) functions for isolated domain communication

Applications

• High-performance server system interconnect switching
• Storage area network infrastructure components
• Enterprise computing platform expansion architectures

Procurement Notes

Verify the specific suffix 'L8' against official Renesas documentation to confirm packaging configuration, as suffixes typically denote reel or tray variations rather than functional changes. Confirm current availability status directly with authorized distributors, as this component may be subject to end-of-life notices or limited stock conditions in the global market.

Selection Notes

Select this component when designing systems requiring 32 lanes of PCIe Gen2 connectivity distributed across eight distinct ports. Ensure the design accommodates the required 1V, 2.5V, and 3.3V power domains. Verify that the PCB layout supports the 484-ball FCBGA footprint and thermal requirements for industrial temperature operation ranges.

Part Context

This part belongs to the IDT 89H series of PCIe switches, which are designed for deterministic system interconnect switching. The series includes variants with different lane counts and port configurations, such as the 89H32NT24AG2 for higher density applications. These devices are commonly used in enterprise infrastructure to expand PCIe connectivity beyond standard root complex limits.

Replacement Considerations

Direct replacements include other 89H32NT variants from Renesas/IDT, such as the 89H32NT8AG2ZCHL8, depending on specific packaging and lead-free requirements. Cross-referencing the exact suffix is critical to ensure mechanical and electrical compatibility.
