Questions

Is there a KiCad symbol and footprint for the ATSAM3U4EA-CU?

Yes. The symbol is EasyEDA_Cloud:ATSAM3U4EA-CU and the footprint Package_BGA:LFBGA-144_10x10mm_Layout12x12_P0.8mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATSAM3U4EA-CU?

LFBGA-144(10x10), with 144 pins. Its footprint is drawn on this page.

Where is the ATSAM3U4EA-CU datasheet?

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

Where can I order the ATSAM3U4EA-CU?

JLCPCB lists it as part C612486, with 1 in stock; the sellers' links on this page open their listings.

What can replace the ATSAM3U4EA-CU?

Parts like it in the library: the XMC4500-E144F1024 AC by Infineon Technologies, the ATSAME70Q21B-CN by Microchip Technology, the ATSAMS70Q21A-CN by Microchip Technology and the XMC4500-E144X1024 AC by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
