89H32NT24BG2ZBHLI

Overview

The Renesas 89H32NT24BG2ZBHLI 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 Non-Transparent Bridging (NTB) functions, movable upstream support, and on-board DMA capabilities. Internal buffering and flow control credits are utilized to maximize bandwidth and handle large payloads efficiently. Designed for industrial applications, it operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput for all ports regardless of loading conditions.
• Supports partitionable switch architecture enabling true multi-root functionality for complex system configurations.
• Integrates multiple Non-Transparent Bridging (NTB) functions to facilitate isolated domain communication.

Applications

• High-performance server system interconnect switching
• Industrial computing network infrastructure
• Storage area network (SAN) connectivity solutions

Procurement Notes

Verify component authenticity through authorized channels due to End-of-Life status. Confirm RoHS compliance requirements as the specific suffix may indicate leaded construction. Validate moisture sensitivity level handling procedures prior to surface mount assembly to prevent package damage during reflow processes.

Selection Notes

Select this model when 32 lanes and 24 ports are required for deterministic switching. Ensure compatibility with PCIe Gen2 specifications for link negotiation. Consider the 484-FCBGA footprint constraints during PCB layout design. Verify thermal management strategies meet the -40°C to +85°C operational envelope for target environments.

Part Context

This component belongs to the IDT/Renesas 89H series of PCIe switches. It serves as a critical node in expanding PCIe topology beyond standard root complex limits. The part integrates advanced bridging features distinct from simple repeater or retimer devices, offering full switching fabric capabilities for enterprise and industrial platforms.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements require verification against updated datasheets from alternative manufacturers or evaluation of adapter solutions.
