89H32NT8AG2ZBHL8

Overview

The Renesas 89H32NT8AG2ZBHL8 is a specialized PCIe switch interface integrated circuit manufactured by Renesas Electronics. It operates on a 3.3V power supply and utilizes a 484-FCBGA package with dimensions of 23x23 mm for surface mount installation. The device supports PCI Express interfaces and functions as a system interconnect switch. It provides 32 lanes and 8 ports, delivering a data rate of 256 Gb/s. The component supports multiple voltage levels including 1 V, 2.5 V, and 3.3 V, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Non-blocking switch architecture optimized for high-performance system interconnect
• Partitionable switch architecture supporting true multi-root configurations
• Supports multiple nontransparent bridging (NTB) functions
• Includes onboard DMA support and internal buffering with flow control credits

Applications

• High-performance system interconnect switching
• Multi-root server architectures
• Data center infrastructure networking

Procurement Notes

Verify the specific suffix ZBHL8 against official Renesas documentation to confirm lead-free status and tray packaging requirements. Confirm current product lifecycle status as this series may be discontinued or subject to change. Ensure compatibility with existing PCB footprint designs 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 system interconnect applications. Consider the 484-FCBGA package constraints and thermal management needs for the 23x23 mm form factor. Verify that the 3.3V I/O and core voltage requirements align with the target system design specifications.

Part Context

This part belongs to the 89H32NT8AG2 family of PCIe switches from Renesas. It shares architectural similarities with other models in the series, such as the 89H32NT24AG2, but differs in port count and lane configuration. The 89H32NT8AG2ZBHL8 specifically denotes the 8-port variant within this generation of interconnect switches.
