LPC11U1x NXP Semiconductors 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.

LPC11U1x NXP Semiconductors 32-bit ARM Cortex-M0 microcontroller For a bus-powered device, the VBUS signal does not need to be connected to the USB_VBUS pin (see Figure 27). The USB_CONNECT function can additionally be connected as shown in Figure 26 to prevent the USB from timing out when there is a significant delay between power-up and handling USB traffic.

Slave mode operation of the on-chip oscillator In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF (Figure 28), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This corresponds to a square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin in this configuration can be left unconnected.
