89H24NT24G2ZAHLI

Overview

The 89H24NT24G2ZAHLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 24 lanes and 24 ports of high-performance, deterministic switching with non-blocking architecture. The device operates at a maximum clock frequency of 125 MHz and supports data rates up to 192 Gb/s. It utilizes a 324-FCBGA package for surface mount installation. Electrical specifications include operating voltages of 1 V, 2.5 V, and 3.3 V. The component functions within a temperature range of -40°C to +85°C and features a 32/64-bit data bus width.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect partitioning
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream configurations
• Includes on-board DMA support with internal buffering and flow control credits

Applications

• High-performance system interconnect switching
• Multi-root support architectures
• PCIe expansion systems requiring deterministic throughput

Procurement Notes

Verify current availability status as the part may be subject to limited supply or factory special orders. Confirm RoHS compliance requirements, as this specific variant is listed as non-compliant in distributor records. Ensure compatibility with existing PCB layouts for the 324-FCBGA package before procurement.

Selection Notes

Select this component when a 24-port PCIe Gen2 switch is required for non-blocking data transfer. Compare against the 89H24NT24G2ZBHLI variant if lead-free certification is mandatory, noting that the ZAHLI suffix indicates non-RoHS status. Verify thermal management capabilities for the FCBGA package within the specified operating temperature range.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches from Renesas. It shares architectural similarities with other models in the family but differs in packaging and compliance suffixes. The device is designed to replace legacy switching solutions in server and storage applications requiring high bandwidth.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Evaluate the 89H24NT24G2ZBHLI for lead-free requirements, though functional equivalence must be verified through official datasheets.
