Procurement Notes

This specific part number is listed as obsolete or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus channels. Ensure compatibility with existing PCB footprints and verify RoHS compliance status through official documentation before procurement planning.

Selection Notes

Select this component when designing systems requiring 32 PCIe Gen2 lanes and 24 ports. Consider the 484-FCBGA package size and thermal requirements. Verify that the design supports the required voltage domains of 1 V, 2.5 V, and 3.3 V. Confirm that the industrial temperature range meets environmental constraints.

Part Context

The 89H32NT24BG2 series belongs to Renesas' PCIe Gen2 switch family. Variants differ by port count, lane configuration, and packaging suffixes indicating lead-free status and carrier type. This model specifically offers 24 ports across 32 lanes, distinguishing it from lower-port variants like the 89H24NT6AG2.

Replacement Considerations

As the part is obsolete, direct substitutes may be limited. Check for newer generations such as PCIe Gen3 or Gen4 switches from Renesas or competitors. Verify pin-to-pin compatibility if considering alternative packages. Review datasheets for functional equivalence in NTB and DMA support.
