Questions

Is there a KiCad symbol and footprint for the ATSAM3U2CA-AU?

Yes. The symbol is EasyEDA_Cloud:ATSAM3U2CA-AU_C81839 and the footprint Package_QFP:LQFP-100_14x14mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATSAM3U2CA-AU?

LQFP-100(14x14), with 100 pins. Its footprint is drawn on this page.

Where is the ATSAM3U2CA-AU datasheet?

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

Where can I order the ATSAM3U2CA-AU?

JLCPCB lists it as part C81839, with 5 in stock; the sellers' links on this page open their listings.

What can replace the ATSAM3U2CA-AU?

Parts like it in the library: the STM32F407VGT6 by STMicroelectronics, the GD32F303VET6 by GigaDevice Semicon Beijing, the GD32F407VET6 by GigaDevice Semicon Beijing and the GD32F407VGT6 by GigaDevice Semicon Beijing.
