I want to use a CYUSB301x controller as a high speed USB 2 device. USB 2 states that the power must not exceed 100mA at enumeration. In the data sheet it states that the power of ICC core is 200mA max. What will the power be during enumeration?

200mA is the maximum current consumed by the FX3 when most of the internal blocks are active and performing data transfers.
It would be less than 100mA during the high speed enumeration.
