89H32NT24AG2ZAHLI8

Overview

The Renesas 89H32NT24AG2ZAHLI8 is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It features a non-blocking architecture optimized for high-performance data throughput. The device supports multiple voltage domains including 1 V, 2.5 V, and 3.3 V. It operates within a temperature range of -40°C to +85°C. The component utilizes a 484-FCBGA package with dimensions of 23x23 mm. Maximum clock frequency is 125 MHz, supporting a total data rate of 256 Gb/s.

Feature Summary

• Non-blocking switch architecture ensuring full line-rate throughput for all ports regardless of loading conditions.
• Partitionable switch design enabling true multi-root support for complex system configurations.
• Support for multiple Nontransparent Bridging (NTB) functions to isolate traffic domains.

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area network fabrics

Procurement Notes

Verify the specific suffix ZAHLI8 against official Renesas documentation to confirm lead-free status and packaging type. Cross-reference the Mouser part number 972-89H32NT24AG2ZAHLI8 for current availability. Confirm RoHS compliance details as some variants may differ. Check for any recent Product Change Notices affecting this specific revision.

Selection Notes

Select this component when 32 lanes and 24 ports are required for PCIe Gen2 connectivity. Ensure the design accommodates the 484-FCBGA footprint and thermal requirements. Verify that the system power budget supports the 1 V, 2.5 V, and 3.3 V rails. Consider the industrial temperature range if operating in harsh environments.

Part Context

This part belongs to the IDT 89H series of PCIe switches, designed for deterministic low-latency switching. It is an evolution of earlier IDT products acquired by Renesas. The 89H32NT24 variant specifically targets high-density switching applications requiring significant port counts without performance degradation under load.
