    Hi Ken,

    No, there is no risk when powering on Vio before Vsup is supplied. Before Vsup is available, the device will be considered off. As long as all pin states remain within absolute maximum values, there will be no risk of damage to the device in this state. 

    Let me know if you have any more questions.
