89H32NT8BG2ZBHLI

Overview

The 89H32NT8BG2ZBHLI is a PCIe Gen2 switch interface IC manufactured by Renesas Electronics. It provides 32 lanes and 8 ports of high-performance, deterministic system interconnect switching with non-blocking architecture. The device supports full line rate throughput for multiple traffic flows regardless of switch loading. It features partitionable architecture for multi-root support, Nontransparent Bridging (NTB), movable upstream support, and on-board DMA. Power supplies include 1V, 2.5V, and 3.3V. Operating temperature ranges from -40°C to +85°C. The component is housed in a 484-FCBGA package.

Procurement Notes

Verify the specific suffix ZBHLI against official Renesas documentation to confirm package type and lead-free status. Confirm current production status as some variants in this family are marked obsolete. Ensure compatibility with existing board designs regarding voltage levels and thermal requirements before procurement.

Selection Notes

Select this component when 32 lanes and 8 ports of PCIe Gen2 switching are required. Consider the FCBGA-484 package constraints for PCB layout. Evaluate power supply requirements for 1V, 2.5V, and 3.3V rails. Compare against other models in the 89H series based on lane count and port density needs.

Part Context

This part belongs to the IDT/Renesas 89H series of PCIe switches. It is related to models like 89H32NT8AG2ZBHLI and 89H32NT8BG2ZAHLGI8. These devices are designed for high-throughput data center and enterprise applications requiring low latency and high reliability.

Replacement Considerations

Check for direct substitutes within the 89H32NT8BG2 family. Verify if older revisions or different suffixes offer equivalent functionality. Consult Renesas for end-of-life notices or recommended new design alternatives.
