89H24NT6AG2ZCHLG

Overview

The 89H24NT6AG2ZCHLG is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 6 ports, supporting up to 192 Gbps of non-blocking throughput. The device operates with supply voltages of 1 V and 3.3 V within an industrial temperature range of -40°C to +85°C. It utilizes a 484-lead FCBGA package measuring 23x23 mm. Key specifications include support for PCIe Gen1 (2.5 GT/s) and Gen2 (5.0 GT/s) speeds, low latency architecture, and internal buffering optimized for large payloads.

Feature Summary

• Partitionable switch architecture enabling true multi-root support through independent logical domains
• Supports multiple Nontransparent Bridging (NTB) functions for communication across external PCIe domains
• Low latency design with internal buffering and flow control credits optimized for maximum bandwidth

Applications

• High-performance server system interconnects requiring deterministic switching
• Storage area networks needing high-throughput data transfer capabilities
• Communication infrastructure equipment utilizing multi-root I/O expansion

Procurement Notes

Verify component authenticity against official Renesas documentation due to the discontinued status of this part number. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB layouts designed for the 484-FCBGA package dimensions. Review end-of-life notifications for any specific transition guidance provided by the manufacturer.

Selection Notes

Select this component when designing systems requiring partitionable PCIe switching with nontransparent bridging capabilities. Consider the 484-FCBGA footprint constraints and thermal management needs for industrial temperature operation. Evaluate power supply requirements for both 1 V and 3.3 V rails before integration into the target hardware platform.
