Thank you both for the feedback. In the short term we’ve updated the document to clarify so hopefully others won’t have the same problem, and are working on a more thorough specification.
FE310-G000 is currently offered in a single package option, a convenient, industry standard 6x6mm 48-lead QFN package (0.4mm pad pitch).
Thanks for being early adopters and apologies for the inconvenience!
