    pull-up resistor needed for self-powered USB CY8C24x39 ?

    gustaaf.verhaegen

      I am trying to use CY8C24894 in a design including the USB interface. I want to use it as a self-powered device.

         

      I read several files on it but one thing is not clear. Do I need to provide an external pull-up resistor to D+ or is that handled by the USBFS module. The supply voltage for my PSoC1 device is 5V.
