89H32NT8AG2ZCHLGI8

Overview

The 89H32NT8AG2ZCHLGI8 is a PCI Express switch interface integrated circuit manufactured by Renesas Electronics Corporation. It operates within the 89H32NT8AG2 series and provides 32 PCIe Gen2 lanes across 8 ports. The device utilizes a non-blocking switch architecture to ensure deterministic system interconnect switching with full line-rate throughput for multiple traffic flows. It supports partitionable switch architectures for multi-root configurations and includes internal buffering and flow control credits optimized for large payloads. The component is housed in a 484-FCBGA package measuring 23x23 mm and requires 1 V, 2.5 V, and 3.3 V power supplies.

Feature Summary

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

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Storage area networks requiring deterministic latency

Procurement Notes

Verify the specific suffix ZCHLGI8 against official Renesas documentation to confirm temperature grade and lead-free status. Confirm current product lifecycle status as this part number may be obsolete or superseded by newer revisions. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this component when 32 lanes and 8 ports of PCIe Gen2 connectivity are required. Consider the 89H32NT24AG2 series if higher port counts are needed. Verify that the design supports the necessary voltage domains of 1 V, 2.5 V, and 3.3 V. Ensure the application benefits from the non-blocking architecture and NTB support features inherent to this family.
