We use MK24FN1M0VDC12 to make the USB2.0 FS device. See attached for the schematic.


We found that there is the large current when there is the USB communication. See attached for the current strike (more than 20mA) caused by the USB communication.

We don't know if this current strike is normal or not, because we do not find the related spec in the datasheet.
