Description
For customers who want to integrate the USB3320 and are looking to the USB3340/USB83340 for future products, this document describes the hardware and software considerations required to accomplish that migration with the least impact to customer design resources. By following the design guidelines outlined in this document, a designer can use a common PCB and software platform that can be used for both the USB3320 and USB3340/USB83340 with nothing more than a change to the Bill of Materials (BOM) being required.
