The USB VBUS specification on the IMXRT1064 says it needs 4.4V - 5.5V which is then dropped to 3V using the internal LDO. In my application, I do not have a 5V supply as I don't need to supply it to the USB peripheral (in effect, I'm connecting to a self powered device).
Will the USB VBUS operate to 3.3V? Or can I supply 3V directly to the VCC_USB_CAP pin and not the VBUS pins? If possible, I'd like to avoid putting another entire supply down.
