89H32NT8BG2ZBHLG

Overview

The Renesas 89H32NT8BG2ZBHLG is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It supports PCIe Gen2 specifications with a maximum clock frequency of 125 MHz, providing 32 lanes and 8 ports. The device operates within a voltage range of 1 V, 2.5 V, and 3.3 V and functions reliably between -40°C and +85°C. Packaged in a 484-FCBGA (23x23) surface-mount format, it facilitates non-blocking data throughput for complex multi-root architectures.

Feature Summary

• Supports partitionable switch architecture enabling true multi-root system configurations
• Provides non-blocking switch architecture optimized for deterministic high-performance system interconnect switching
• Integrates multiple Nontransparent Bridging (NTB) functions for isolated domain communication

Applications

• High-performance server system interconnects requiring multi-root support
• Storage area networks utilizing non-transparent bridging for data isolation
• Enterprise infrastructure equipment demanding low-latency PCIe switching

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure proper handling procedures are followed given the fine-pitch FCBGA package requirements and lead-free soldering specifications.

Selection Notes

Select this model when an 8-port, 32-lane PCIe Gen2 switch is required for partitionable multi-root environments. Compare against sibling variants like the 89H32NT8AG2ZBHLG regarding specific suffix differences such as packaging type or temperature grade. Validate that the 484-FCBGA footprint matches the target PCB design constraints and thermal management capabilities.
