Hi,

Currently I use mc9s12xdt512 controller.

I need to have different power supply for "regulator power input" and "I/O supply"

The solution would be as follow:

VDDR (Regulator power input) 3.3V

VDDA (Analog power supply) 5V

VDDX (I/O supply) 5V

VRH (Reference voltage) 5V.

Is it possible for the chip to work under this condition?

 

thank you
