89H32NT24AG2ZCHLGI

Overview

The 89H32NT24AG2ZCHLGI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 24 switch ports, supporting a maximum clock frequency of 125 MHz with a data rate of 192 Gb/s. The device operates on supply voltages of 1 V, 2.5 V, and 3.3 V. It features a 484-lead FCBGA package (23x23 mm) designed for surface mount installation. The component supports a commercial temperature range from -40°C to +85°C and includes a 32/64-bit data bus width.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect applications
• Partitionable switch architecture enabling true multi-root support capabilities
• Supports multiple nontransparent bridging functions (NTB) and movable upstream configurations

Applications

• High-performance server system interconnect switching
• Storage area network (SAN) infrastructure
• Enterprise computing platforms requiring deterministic latency

Procurement Notes

Verify the specific ordering suffix against current manufacturer documentation to confirm lead-free status and packaging type. Confirm RoHS compliance details as they vary by suffix. Check for obsolescence notices or product change notifications prior to procurement. Ensure compatibility with existing PCB footprint designs for the 484-FCBGA package.

Selection Notes

Select this component when a high-port-count PCIe Gen2 switch is required for non-blocking throughput. Verify that the design accommodates the 484-FCBGA package dimensions and thermal requirements. Ensure the system power budget aligns with the 1V, 2.5V, and 3.3V supply rails. Confirm that the commercial temperature grade meets the operational environment specifications.

Part Context

This part belongs to the 89H32NT24AG2 family of PCIe switches. Variations in the suffix indicate differences in packaging (tray vs. reel), lead-free status, and temperature grade. The base model 89H32NT24AG2 defines the core switching functionality and lane configuration shared across the series.

Replacement Considerations

Direct replacements are limited due to the specific 484-FCBGA form factor and legacy Gen2 specification. Review the 89H32NT24AG2 family variants for identical electrical characteristics but different packaging or environmental ratings. Newer generation switches may require significant redesign.
