Questions

Is there a KiCad symbol and footprint for the ATSAML21E16B-MU?

Yes. The symbol is MCU_Microchip_SAML:ATSAML21E16B-MUT and the footprint Package_DFN_QFN:QFN-32-1EP_5x5mm_P0.5mm_EP3.6x3.6mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the ATSAML21E16B-MU?

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

Where is the ATSAML21E16B-MU datasheet?

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

Where can I order the ATSAML21E16B-MU?

JLCPCB lists it as part C2053336, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ATSAML21E16B-MU?

Parts like it in the library: the ATSAMD21E18A-MUT by Microchip Technology, the ATSAML21E18B-MU by Microchip Technology, the ATSAMD21E16B-MU by Microchip Technology and the ATSAMD21E17D-MU by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
