I am using a I.MX 6 SoloX processor with a MMPF0200 PMIC. I would like to use the pre-programmed Device F0. My problem is now, that there is no default voltage which fits the requirements for the VDD_HIGH voltage Domain.
Now, I am able to use VGEN1,2,5 or 6. The problem is now, that the VDD_HIGH-Domain powers the clock generation. So, the voltage has to be correct at startup an cannot be overwritten in Software. VGEN1&2 can't be used because the voltage would be too low. VGEN5&6 are right on the limits of the recommended power levels. So, if the level would wobble a bit (which they always will) it is possbile that both voltages violate the Voltage contraints. VGEN5 cant be used because the maximum current is a bit too low (100mA when max. 125mA needed, chapter 4.1.5)
But: In the IM.X 6 SoloX Industrial Application Datasheet Chapter 4.1.6 all test cases use 3.3V to Power VDD_HIGH.
So my question is: Is it guaranteed that the Processor will start up if I apply VGEN6 with 3.3V to this Input even if it may be a bit higher?

Hi DBMicro
yes it will start up, however for longterm reliability it is not recommended to
use higher voltages than recommended by datsheet.
