89H24NT24AG2ZBHLGI

Overview

The Renesas 89H24NT24AG2ZBHLGI is a PCIe Gen2 system interconnect switch providing 32 lanes and 24 ports. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 484-lead FCBGA package. The device supports multiple voltage domains including 1V, 2.5V, and 3.3V. It delivers non-blocking throughput with internal buffering and flow control credits optimized for large payloads.

Feature Summary

• Supports partitionable switch architecture for true multi-root functionality
• Enables movable upstream port configuration for flexible system design
• Integrates on-board DMA support to reduce processor overhead

Applications

• High-performance server system interconnects
• Storage area network (SAN) switching fabrics
• Enterprise infrastructure requiring multi-root topology

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details as the specific suffix indicates lead-free composition. Validate moisture sensitivity level handling requirements during assembly to prevent package damage.

Selection Notes

Select this model when 24 downstream ports and 32 upstream lanes are required. Ensure the design accommodates the 484-pin FCBGA footprint. Verify that the application benefits from non-transparent bridging functions and movable upstream capabilities compared to fixed architectures.

Part Context

This part belongs to the 89H24NT24G2 series of PCIe switches. It shares core switching logic with variants differing in packaging or thermal grades. The ZBHLGI suffix denotes specific lead-free and industrial/commercial grade attributes within the broader product family.

Replacement Considerations

Publicly confirmed direct substitutes are not available. Consider evaluating the 89H24NT24AG2ZCHLGI for potential pin-compatible alternatives if supply constraints exist, though verification against specific datasheet revisions is mandatory.
