89H32NT8AG2ZBHLGI

Overview

The 89H32NT8AG2ZBHLGI is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 8 ports, supporting a maximum clock frequency of 125 MHz with a data rate of 256 Gb/s. The device operates within a temperature range of -40°C to +85°C and utilizes an FCBGA-484 package. Power requirements include supply voltages of 1 V, 2.5 V, and 3.3 V. This component is classified as a PCI interface IC designed for high-performance switching applications.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture for true multi-root support
• Supports multiple nontransparent bridging functions (NTB)
• Features on-board DMA support and internal buffering

Applications

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

Procurement Notes

Verify the specific suffix ZBHLGI against official Renesas documentation to confirm lead-free status and moisture sensitivity level. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as legacy components may have varying environmental declarations. Check for end-of-life notices or product change notifications prior to procurement.

Selection Notes

Select this component when a 32-lane, 8-port PCIe Gen2 switch is required for partitionable multi-root environments. Ensure the design supports the necessary 1 V, 2.5 V, and 3.3 V power rails. Verify that the FCBGA-484 footprint fits the PCB layout constraints and that thermal management meets the -40°C to +85°C operating range requirements.

Part Context

This part belongs to the 89H32NT8AG2 series of PCIe switches. It shares architectural similarities with other models in the family, such as the 89H32T8G2ZCBLI, but differs in lane count, port configuration, and specific feature sets like NTB support. It is distinct from lower-density variants like the 89H24NT6AG2 series.
