Procurement Notes

This component is officially listed as End-of-Life (EOL). Availability is restricted, and it may not be sold in all regions by major distributors. Verification of current stock status and alternative sourcing channels is required before procurement planning. Confirm the specific suffix ZBHLGI8 matches design requirements as EOL status limits long-term supply assurance.

Selection Notes

Select this part for designs requiring 32 lanes and 8 ports of PCIe Gen2 connectivity. Ensure the PCB layout accommodates the 484-FCBGA (23x23 mm) footprint. Verify power delivery for 1V, 2.5V, and 3.3V rails. Consider the EOL status when defining product lifecycles. Check if partitionable architecture needs align with multi-root support requirements.

Part Context

The 89H32NT8AG2ZBHLGI8 belongs to the 89H32NT8AG2 series of PCIe switches from Renesas (formerly IDT). This series focuses on deterministic switching with low latency. The base model 89H32NT8AG2 defines the core functionality, while the suffix indicates packaging and compliance variations. It is part of the broader portfolio of PCI interface ICs designed for enterprise and storage applications.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is End-of-Life, engineers must evaluate newer generations from Renesas or other vendors. Cross-reference pinouts and electrical specifications carefully if selecting a functional equivalent.
