89H32NT8BG2ZBHLGI

Overview

The 89H32NT8BG2ZBHLGI is a PCI Express Gen2 system interconnect switch manufactured by Renesas Electronics. It provides 32 PCIe lanes and 8 ports, delivering non-blocking throughput for high-performance applications. The device operates with supply voltages of 1V, 2.5V, and 3.3V, supporting data rates up to 256 Gb/s. It utilizes a 484-ball FCBGA package measuring 23x23 mm. The component supports an industrial temperature range from -40°C to +85°C and features internal buffering and flow control credits optimized for large payloads.

Feature Summary

• Non-blocking switch architecture ensuring full line rate throughput regardless of switch loading
• Partitionable switch architecture enabling true multi-root support
• Support for multiple Nontransparent Bridging (NTB) functions
• On-board DMA support with movable upstream capability

Applications

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

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as ordering codes define specific thermal grades and packaging types. Confirm current lifecycle status, as this model may be obsolete or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints and voltage domains before procurement.

Selection Notes

Select this component when 32 lanes and 8 ports are required for Gen2 speeds. Compare against the 89H32NT24AG2 series if higher port counts are needed. Verify that the 484-FCBGA package fits the design constraints. Check for alternative retimer or switch solutions if Gen3/Gen4 performance is eventually required.

Part Context

This part belongs to the IDT 89H32NT8AG2 family of PCIe switches. It shares architectural similarities with other members like the 89H32NT24AG2 but differs in port count. The family is designed for deterministic system interconnects in computing and communications infrastructure.
