Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Request official datasheets and errata documents prior to integration. Ensure supply chain compliance with RoHS and REACH regulations. Validate lead times directly with the manufacturer due to potential production variations.

Selection Notes

Select this component when industrial temperature stability is required for USB 3.2 Gen 1 applications. Choose this model over commercial variants if operation below 0°C is necessary. Verify that the four-port configuration meets system bandwidth requirements. Ensure the PCB layout supports the VQFN-100 thermal pad design. Confirm compatibility with existing Power Delivery controllers if advanced power management is needed.
