I have successfully designed a few boards using Atmel processors in an MLF32 package. This has a 0.5mm pin pitch and it causes a few problems (search for my OPs for details), but they are not totally insurmountable as you will see from the OPs and follow-up posts.
Obviously one needs to design the footprint correctly, but despite my MLF footprint being pretty weird compared to lower density packages, designing it in kicad was not a problem. Does that answer your question? Regards, Robert.
