89H24NT6AG2ZCHLG8

Overview

The Renesas 89H24NT6AG2ZCHLG8 is a PCIe Gen2 system interconnect switch providing 24 lanes and 6 ports. It features a non-blocking architecture with 192 Gbps switching capacity, supporting 5.0 GT/s data rates. The device utilizes a 484-lead FCBGA package (23x23 mm) and operates on 1V, 2.5V, and 3.3V supplies. It supports industrial temperature grades (-40°C to +85°C), lead-free construction, and reel packaging. Key capabilities include partitionable switching for multi-root support, Nontransparent Bridging (NTB), movable upstream ports, and internal flow control optimized for large payloads.

Feature Summary

• Partitionable switch architecture enabling true multi-root support through dynamic reconfiguration of downstream, upstream, and non-transparent bridge ports.
• Support for multiple Nontransparent Bridging (NTB) functions allowing communication between switch partitions, external PCIe domains, or CPUs.
• Movable upstream port capability that enhances system flexibility by allowing upstream ports to move within or between switch partitions.

Applications

• High-performance server systems requiring deterministic cross-domain communication
• Storage area networks needing high-throughput I/O expansion
• Multi-host intelligent I/O systems requiring logical isolation

Procurement Notes

Verify the specific suffix ZCHLG8 against official Renesas documentation to confirm lead-free status and industrial temperature grade. Confirm reel packaging requirements with authorized distributors. Check current lifecycle status as this component family may be obsolete or subject to PCN changes. Ensure compatibility with existing PCB footprints for the 484-FCBGA package.

Selection Notes

Select this model when 24 lanes and 6 ports are required for PCIe Gen2 applications. Choose over the 89HPES24NT6A variant if industrial temperature range and lead-free compliance are mandatory. Consider the 89H24NT24G2 series if higher port density is needed. Verify NTB requirements match the six supported endpoints per switch.

Part Context

This part belongs to the IDT/Renesas 89HPES24NT6A family of PCIe switches. It shares core architecture with variants like 89H24NT6AG2ZBHLGI but differs in packaging, temperature grade, and environmental compliance. The ZCHLG8 suffix specifically denotes industrial grade, lead-free composition, and reel carrier type.

Replacement Considerations

Direct substitutes include other suffixes of the 89H24NT6AG2 family such as 89H24NT6AG2ZBHLGI for commercial/industrial options. For pin-compatible alternatives, verify the 89HPES24NT6A series. No direct cross-manufacturer replacements exist due to proprietary architecture.
