Voltage power up sequence

[marijanvesligaj]

What is the proper voltage power up sequence for MX6SoloX CPU?

As stated in datasheet, VDD_HIGH and VDD_SNVS can be powered up simuntaneously. What about other voltages then, especially core voltage and 3.3V IO.

Can everything be powered up at the same time?

Hi Marijan

everything can not be powered up at the same time,

datasheet also describes restrictions for VDD_ARM_IN and VDD_SOC_IN

in case external POR. In general recommended to follow i.MX6SX SDB deisgn

(with MMPF0100F6)

IMX6SOLOX-SABRESDB-DESIGNFILES

Best regards

igor
