5V tolerant digital inputs on K60?

[pozz]

Are digital K60 I/O 5V tolerant when used as inputs?

In the datasheet the Absolute Maximum Rating is -0.3V to +5.5V, so it seems it would be safe to interface a 5V signal.

What do you think?

I think that's fine, but I haven't actually tried it myself.

Anyone from Freescale can confirm?

"All 5 volt tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode connection to VDD." So yes, they are 5V tolerant. You just have to find out which of the I/O pins are 5V tolerant.

Does anyone know if the ADC inputs on the Kinetis 40  series are 5V tolerant? The data says the digital I/Os only, not the analog inputs are 5V tolerant. The definition of analog is unclear - some of the ADC inputs have digital input options too.
