I tried using the product selector and it does allow one to choose "FS/HS" under the USB column, but the parts it narrows the list to are primarily full-speed only parts (even though they're in the table as "FS/HS"). I did find a couple of family pages:
These provide some nice text about there being some parts that support high-speed USB 2.0 and, if I select the FS/HS USB option, give me some parts that support high-speed USB 2.0, but it's far from clear that this is a complete list of parts with that support.
I tried a live chat and the support technician's answer was "You're right, there doesn't seem to be a way to narrow down to just the high-speed parts. Maybe you should enter a question in the forums". So, here I am.
Is there a list somewhere that indicates which active Kinetis parts support high-speed USB2.0 or are the few parts listed on the above mentioned product pages the total of the parts with high-speed USB2.0 support?
