Are the parts 5-Volt tolerant? I have looked through the documentation
and didn't see it mentioned.

If they  do not mention it, usually that means no.

 Still, the number of vendors who offer not only 5V tolerant, but also 5V operating M0's is increasing rapidly, Infineon, Nuvoton, ABOV, Holtek, Fujitsu (etc), so that means more choice.

 Notice how the USA vendors seem to be the slowest to grasp this ?

Answer I got back is no, the I/O is not 5-Volt tolerant.

Shame, relegates an otherwise attractive part, back into the 'also rans'.

I've updated the article to reflect that the I/O are not 5V tolerant.
