89H32NT24BG2ZCHL

Overview

The Renesas 89H32NT24BG2ZCHL 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 integrated to maximize bandwidth efficiency with large payloads. Operating temperatures range from -40°C to +85°C, and it utilizes a 484-lead FCBGA package.

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 flexible system configurations.
• Integrated on-board DMA and internal buffering mechanisms to optimize latency and power consumption.

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to limited market availability. Confirm lead-free status and moisture sensitivity level prior to assembly. Review official datasheets for specific handling requirements and soldering profiles to ensure reliable integration into final designs.

Selection Notes

Select this model when 32 lanes and 24 ports are required for PCIe Gen2 environments. Ensure the 484-FCBGA footprint fits the PCB layout constraints. Verify that the industrial temperature range meets operational requirements. Consider alternative part numbers within the same family if different port counts or packaging options are needed.

Part Context

This component belongs to the 89H series of PCIe switches manufactured by Renesas Electronics. It is designed for enterprise and industrial applications demanding high bandwidth and low latency.
