89H32NT8BG2ZAHLGI8

Overview

The Renesas 89H32NT8BG2ZAHLGI8 is a specialized PCI Express switch interface integrated circuit designed for high-performance system interconnect applications. It features 32 PCIe Gen2 lanes and supports 8 ports, delivering a total data rate of 256 Gb/s. The device operates with supply voltages of 1 V, 2.5 V, and 3.3 V. It is housed in a 484-FCBGA package measuring 23x23 mm, suitable for surface mount installation. The component functions within an operating temperature range of -40°C to +85°C and utilizes a 32/64-bit data bus width.

Feature Summary

• Provides non-blocking switching architecture optimized for high-performance system interconnect partitioning.
• Supports true multi-root functionality through a partitionable switch architecture.
• Includes internal buffering and flow control credits optimized for maximum bandwidth and large payloads.

Applications

• High-performance system interconnect switching
• PCIe-based server architectures requiring multi-root support
• Enterprise storage networking solutions

Procurement Notes

Verify the specific suffix GI8 against official Renesas documentation to confirm lead-free status and industrial temperature grade specifications. Confirm current lifecycle status as this part may be discontinued or subject to last-time buy restrictions. Ensure compatibility with existing PCB footprints for the 484-FCBGA package before procurement.

Selection Notes

Select this component when a 32-lane, 8-port PCIe Gen2 switch is required for deterministic traffic flow. Compare against other 89H series variants based on port count and lane density requirements. Verify that the 1V, 2.5V, and 3.3V power domains align with the target system's power management design constraints.

Part Context

This part belongs to the Renesas 89H series of PCIe switches, which are engineered for scalable system interconnects. It succeeds earlier IDT-branded products following the acquisition. The 89H32NT8 variant specifically targets applications needing moderate port density with high throughput capabilities compared to lower-lane counterparts.
