Dear community,
I have a question about power-up sequence about VDD_HIGH_IN .
[Background]
In the datasheet , it is described that
VDD_SNVS_IN supply must be turned ON before any other power supply. It may be connected
(shorted) with VDD_HIGH_IN supply.
I did not see any sequence requirements on VDD_HIGH_IN.
[Question]
When VDD_SNVS_IN is connected with VDD_HIGH_IN ,
does the VDD_HIGH_IN have to turned on before any other power supply ?
Best Regards,

Solved! Go to Solution.
VDD_SNVS_IN has to be turned on before anything else. If VDD_HIGH_IN is connected to VDD_SNVS_IN, it will be turned on practically at the same time.

Hi SerchMX,
Could you let me know the sequence of VDD_SNVS_IN and VDD_HIGH_IN when these are not connected also?
I guess VDD_SNVS_IN -> VDD_HIGH_IN -> other supplies is correct sequence.
Is this correct?
And I guess if user don't preserve this sequence, i.MX6 cannot power up correctly and i.MX6 is damaged.
Is this correct?
