89H32NT8AG2ZCHLI8

Overview

The 89H32NT8AG2ZCHLI8 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. It operates within a temperature range of -40°C to +85°C and utilizes a 484-FCBGA package. Power supplies include 1V, 2.5V, and 3.3V rails. Maximum clock frequency is 125 MHz.

Feature Summary

• Non-blocking switch architecture optimized for high performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple Nontransparent Bridging (NTB) functions
• Features movable upstream support and on-board DMA capabilities

Applications

• High-performance server system interconnect
• Storage area network infrastructure
• Telecommunications base station backplanes

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or end-of-life. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Check for specific ordering suffix variations that may affect packaging or lead-free status. Ensure compatibility with existing board designs regarding voltage levels and thermal requirements.

Selection Notes

Select this component when designing systems requiring 32 PCIe Gen2 lanes with eight downstream ports. Consider the 484-FCBGA package constraints during PCB layout. Evaluate power delivery networks for the 1V, 2.5V, and 3.5V domains. Verify that the application benefits from non-blocking throughput and low latency characteristics inherent to the switch architecture.

Part Context

This model belongs to the IDT 89H32NT family of PCIe switches. It shares architectural similarities with other variants in the series but differs in port count and lane configuration. The 'G2' suffix indicates PCIe Generation 2 support. The 'ZCHLI8' suffix typically denotes specific packaging, temperature grade, and reel/tray options.
