    LPC11U1x
    32-bit ARM Cortex-M0 microcontroller
    11. Application information
    11.1 Suggested USB interface solutions
    The USB device can be connected to the USB as self-powered device (see Figure 26) or
    bus-powered device (see Figure 27).
    On the LPC11U1x, the PIO0_3/USB_VBUS pin is 5 V tolerant only when VDD is applied
    and at operating voltage level. Therefore, if the USB_VBUS function is connected to the
    USB connector and the device is self-powered, the USB_VBUS pin must be protected for
    situations when VDD = 0 V.
    If VDD is always greater than 0 V while VBUS = 5 V, the USB_VBUS pin can be connected
    directly to the VBUS pin on the USB connector.
    For systems where VDD can be 0 V and VBUS is directly applied to the VBUS pin,
    precautions must be taken to reduce the voltage to below 3.6 V, which is the maximum
    allowable voltage on the USB_VBUS pin in this case.
    One method is to use a voltage divider to connect the USB_VBUS pin to the VBUS on the
    USB connector. The voltage divider ratio should be such that the USB_VBUS pin will be
    greater than 0.7VDD to indicate a logic HIGH while below the 3.6 V allowable maximum
    voltage.
    For the following operating conditions
    VBUSmax = 5.25 V
    VDD = 3.6 V,
    the voltage divider should provide a reduction of 3.6 V/5.25 V or ~0.686 V.
