Questions

Is there a KiCad symbol and footprint for the ATSAML21G16B-MU?

Yes. The symbol is MCU_Microchip_SAML:ATSAML21G16B-MUT and the footprint Package_DFN_QFN:QFN-48-1EP_7x7mm_P0.5mm_EP5.15x5.15mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATSAML21G16B-MU?

VQFN-48-EP(7x7), with 49 pins. Its footprint is drawn on this page.

Where is the ATSAML21G16B-MU datasheet?

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

Where can I order the ATSAML21G16B-MU?

JLCPCB lists it as part C2055130, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATSAML21G16B-MU?

Parts like it in the library: the ATSAML21G17B-MU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
