89H32NT24AG2ZCHLG8

Overview

The 89H32NT24AG2ZCHLG8 is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 24 ports of high-performance, deterministic switching with non-blocking architecture. The device supports full line-rate throughput for multiple traffic flows regardless of load. It operates at a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. Power supply requirements include 1 V, 2.5 V, and 3.3 V rails. The component is housed in a 484-FCBGA package measuring 23x23 mm. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture enabling true multi-root support
• Supports multiple Nontransparent Bridging (NTB) functions
• Includes on-board DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect partitioning
• Multi-root server architectures
• Storage area networks requiring deterministic latency
• Communications infrastructure equipment

Procurement Notes

Verify the specific suffix ZCHLG8 against official Renesas documentation to confirm lead-free status and tray packaging details. Confirm current product lifecycle status as this part number may be obsolete or restricted. Ensure compatibility with existing board designs regarding the 484-FCBGA footprint and thermal requirements before procurement.

Selection Notes

Select this component when 32 lanes and 24 ports are required for PCIe Gen2 systems. Consider the FCBGA package size and pin count for PCB layout constraints. Evaluate power budget requirements for the 1V, 2.5V, and 3.3V domains. Verify if partitionable architecture features align with system topology needs.

Part Context

This part belongs to the 89H series of PCIe switches from Renesas (formerly IDT). It is designed for enterprise and communications applications demanding low latency and high bandwidth. The AG2 designation indicates PCIe Gen2 capability. The ZCHLG8 suffix specifies the package type, temperature grade, and compliance attributes.

Replacement Considerations

Check Renesas PCNs for obsolescence notices. Potential substitutes within the same family include other 89H32 variants with different port counts or lane configurations. Verify electrical and mechanical compatibility before substitution.
