Does the FRDM-K64F have 5V-tolerant GPIOs?

Well I'm just adding this information here since we can't edit the actual page. The answer is yes!

My humble contribution:

-page 6, table on the top http://cache.freescale.com/files/microcontrollers/doc/data_sheet/K64P144M120SF5.pdf

To clarify, the digital IO pins are 5V tolerant, the analog ones are not.

Since all the analogue capable pins are are digital pins, it is safer to restrict FRDM-K64F to 3.3V, max.

If you look at the table referenced by Miloje, there's a note:

"Analog pins are defined as pins that do not have an associated general purpose I/O port function."

So the full story seems to be that it's only the pins that are analog-ONLY that have a problem with 5V.
