Do all SAMD21G18A - XXXX work if i install arduino bootloader?

Using Arduino Installation & Troubleshooting
#1

Hello i am going to make my own pcb for my personal project and and going to use the SAMD21G18A like the one used in arduino nano IOT 33.

When i searched digikey there seems to be multiple variants and i do not know if all them will work,

Please look at this link from Digi-key

Do any of this work and i will just choose the package that fits me ??

What are the difference anyway i look at the table and can only find that the temperature tolerance is different

They differ only in the package and temperature ranges they are rated for.

So I should theoretically be able to upload a bootloader to any one of them right ?

I'm not sure how programming is handled on the Nano IOT 33, so I can't answer that. If that's what's done on the Nano IOT 33, then yes. But I know some of the new boards are using a separate chip to act as a go-between between the serial port and a programming interface on the chip. I don't know if these are one of them.
