I would like to make a PCB to develop with both ATSAMD20 and ATSAML21 using QFN32 package.
According datasheet, it seems they are both pin-to-pin compatible, except for Vsw pin in SAML21 which suggest should be left open for Linear power mode or conencted to Vcc through an inductor, when switching power mode is used. This pin is tied to Vcc in the SAMD20. I would just have same circuit for bith chips which should require to connect Vsw to Vcc directly. WOuld this be a problem for the SAML21?
Thanks in advance
