89H24NT6AG2ZBHLGI

Overview

The 89H24NT6AG2ZBHLGI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 6 ports of high-performance, deterministic switching with non-blocking architecture for full line-rate throughput. The component operates on 3.3V power and utilizes a 484-FCBGA package measuring 23x23 mm. It supports industrial temperature grades and includes features such as movable upstream support, onboard DMA, and internal buffering optimized for large payloads.

Feature Summary

• Non-blocking switch architecture ensures full line-rate throughput for multiple traffic flows regardless of switch loading.
• Partitionable switch architecture enables true multi-root support within the system.
• Supports multiple Nontransparent Bridging (NTB) functions for isolated domain communication.
• Includes onboard DMA capabilities and internal flow control credits to optimize bandwidth.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• I/O expansion systems requiring peer-to-peer data transfer

Procurement Notes

Verify the specific suffix ZBHLGI confirms the industrial temperature grade and lead-free status. Confirm current availability as this part number may be obsolete or subject to limited supply. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this component when 24 PCIe Gen2 lanes and 6 ports are required for deterministic switching. Consider the partitionable architecture if multi-root support is necessary. Verify that the 3.3V power requirement aligns with the target system design and that the FCBGA package fits the mechanical constraints.

Part Context

This device belongs to the 89H24NT6AG2 series of PCIe switches. Variants in this family differ primarily by packaging type (Tray vs. Reel), temperature grade (Commercial vs. Industrial), and lead-free status. The ZBHLGI suffix specifically denotes the industrial grade, lead-free version packaged in trays.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Check manufacturer announcements for end-of-life notices or recommended upgrades within the same product family.
