89H32NT8AG2ZCHLI

Overview

The 89H32NT8AG2ZCHLI is a PCIe Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic switching with non-blocking architecture. The device supports full line-rate throughput for multiple traffic flows regardless of load. Key features include partitionable switch architecture for multi-root support, multiple Nontransparent Bridging (NTB) functions, movable upstream support, on-board DMA, and internal buffering with flow control credits optimized for large payloads. It operates at a maximum clock frequency of 125 MHz with data rates up to 256 Gb/s. Power supplies are 1 V, 2.5 V, and 3.3 V. Operating temperature ranges from -40°C to +85°C. Package is FCBGA-484.

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions and movable upstream
• On-board DMA support with internal buffering and flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Data center infrastructure requiring low latency and high bandwidth

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Check datasheet revisions for any errata or technical updates. Confirm RoHS compliance and moisture sensitivity level requirements for assembly processes. Validate pinout compatibility if replacing existing designs. Ensure supply chain stability as availability may be limited.

Selection Notes

Select this model when 32 lanes and 8 ports are required for PCIe Gen2 systems. Consider the FCBGA-484 package constraints for PCB layout. Evaluate power budget for 1V, 2.5V, and 3.3V rails. Compare against other 89H series variants like 89H32NT24AG2 for port count differences. Verify thermal management needs for industrial temperature range operation.
