89H32NT8BG2ZCHLG

Overview

The Renesas 89H32NT8BG2ZCHLG is a PCI Express switch interface IC manufactured by Renesas Electronics. It supports up to 125 MHz clock frequency and features 32 lanes across 8 ports. The device operates within a voltage range of 1 V, 2.5 V, and 3.3 V for both minimum and maximum specifications. It is designed for surface mount installation and functions reliably between -40°C and +85°C. This component is classified as a PCIe switch and is currently listed as obsolete.

Feature Summary

• Provides high-performance system interconnect switching capabilities
• Supports multiple traffic flows with non-blocking throughput
• Enables true multi-root support through partitionable architecture

Applications

• High performance system interconnect
• PCIe switch applications
• Multi-root server architectures

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted, and Mouser indicates it is not sold in certain regions. Verification of current stock status and alternative sourcing channels is required before procurement planning. Check official distributor catalogs for last-time buy information or end-of-life notifications.

Selection Notes

Select this part only if legacy compatibility with 32-lane, 8-port PCIe Gen2 switches is required. Verify that the 484-FCBGA package fits the board layout constraints. Ensure design supports the specified 1V, 2.5V, and 3.3V power domains. Confirm thermal management meets the -40°C to +85°C operating range requirements for the target environment.

Part Context

The 89H32NT series includes variants like the 89H32NT24AG2 and 89H32NT8BG2ZCHLG. These are PCIe Gen2 system interconnect switches from IDT/Renesas. The 89H32NT8BG2ZCHLG specifically offers 32 lanes and 8 ports. It shares architectural similarities with other parts in the family but differs in port count and specific suffix configurations.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. As the product is obsolete, engineers should consult Renesas for recommended replacements or evaluate newer generations of PCIe switches from the same manufacturer.
