Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary market distributors. Verify RoHS compliance status and moisture sensitivity level (MSL 3) before procurement. Confirm package integrity and lead condition upon receipt due to potential long-term storage conditions associated with discontinued parts.

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 package dimensions of 23x23 mm. Verify that the power delivery network supports the specified 1V, 2.5V, and 3.3V rails. Consider thermal management solutions suitable for the industrial temperature range of -40°C to +85°C during the design phase.

Part Context

The 89H32NT8BG2ZCHLI8 belongs to the Renesas 89H series of PCI Express switches, which are engineered for deterministic data transfer in complex computing environments. This specific suffix indicates a commercial temperature grade and tray packaging variant. It is part of a lineage of switches supporting Gen2 speeds, often used in legacy or maintained enterprise systems where backward compatibility and stable performance are critical.

Replacement Considerations

Direct replacements are limited due to the obsolete status. Evaluate newer generations such as the 89HPES series or other Renesas PCIe switches with compatible lane counts and port configurations. Ensure pin-to-pin compatibility if substituting within the same package type, and verify that the replacement supports the required PCIe Gen2 protocol and multi-root features.
