Power supply from eva board

[pietroserao]

Good morning i have some questions.

I'm using a FRDMPK 144-Q100 S32k144 Evaluation board.

1) Can this microcontroller works with a 3.3V supply voltage?

2) Can i set the 3,3 V VDD voltage only using the evaluation board, without using external power supply?

    There is some setup?

Thank you.

Pietro,

Yes this MCU can operate down to 2.7V

There is an unpopulated jumper at J10 which can allow to select between 3.3V and 5.0V. You'll need to remove the R64 which is a zero-ohm jumper that directly connects 5.0V to the micro - this needs to be removed so you can make a selection for 3.3V

Schematic attached.
