89H32NT8BG2ZAHLGI

Overview

The Renesas 89H32NT8BG2ZAHLGI 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. The device provides 32 lanes and 8 ports, enabling non-blocking data throughput. It operates within a voltage range of 1 V to 3.3 V and functions reliably between -40°C and +85°C. The component utilizes a 484-FCBGA package with dimensions of 23x23 mm, supporting surface mount installation.

Feature Summary

• Supports partitionable switch architecture for true multi-root capability
• Enables multiple nontransparent bridging (NTB) functions
• Provides on-board DMA support for efficient data transfer

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Nontransparent bridging implementations

Procurement Notes

Verify the specific suffix GI against official Renesas documentation to confirm exact packaging and material compliance details. Confirm current lifecycle status as distributor listings may indicate limited availability or end-of-life conditions. Ensure compatibility with required voltage domains before integration into the design.

Selection Notes

Select this component when 32 lanes and 8 ports are required for PCIe Gen2 systems. Consider the FCBGA-484 package constraints during PCB layout. Verify that the operating temperature range meets environmental requirements. Compare against other models in the 89H series if different port counts or lane configurations are needed.

Part Context

This part belongs to the Renesas IDT 89H series of PCIe switches. It shares architectural similarities with other models like the 89H32NT24AG2 but offers a reduced port count. The series is designed for deterministic low-latency switching in computing and storage environments.
