Supply voltage for STM32 USB application

I require to make STM32 based USB application.STM32 is capable of operating at 2-3.6V.Does it mean that USB can work within this voltage range or it requires a voltage translator to work?

Dear menka,
STM32 USB function is Compliant with the USB 2.0 Full Speed specification as defined by the www.usb.org. Therefore the function is guaranteed from VDD = 2.7V to 3.6 Volts. Having a VDD below 2.7Volts is not supported by STM32 on all temperatures ranges an all worst case conditions like silicon variations etc.. STOne-32
