Questions

Is there a KiCad symbol and footprint for the USB3300-EZK?

Yes. The symbol is Interface_USB:USB3300-EZK and the footprint Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.45x3.45mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the USB3300-EZK?

QFN-32-EP(5x5), with 33 pins. Its footprint is drawn on this page.

Where is the USB3300-EZK datasheet?

Microchip Technology publishes it: the Datasheet link on this page opens it.

Where can I order the USB3300-EZK?

JLCPCB lists it as part C108954, with 945 in stock; the sellers' links on this page open their listings.

What can replace the USB3300-EZK?

Parts like it in the library: the USB3300-EZK-TR by Microchip Technology, the CY7C65215-32LTXI by Infineon Technologies, the CY7C65213A-32LTXI by Infineon Technologies and the CY7C65213-32LTXI by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the USB3300-EZK?
