LPC11U1x
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.
Remark: When a bus-powered circuit as shown in Figure 27 is used, configure the
PIO0_3/USB_VBUS pin for GPIO (PIO0_3) in the IOCON block to ensure that the
USB_CONNECT signal can still be controlled by software. For details on the soft-connect
feature, see the LPC11U1x user manual (Ref. 1).
Remark: When a self-powered circuit is used without connecting VBUS, configure the
PIO0_3/USB_VBUS pin for GPIO (PIO0_3) and provide software that can detect the host
presence through some other mechanism before enabling USB_CONNECT and the
soft-connect feature. Enabling the soft-connect without host presence will lead to USB
compliance failure.
11.2 XTAL input
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
Ci = 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground Cg which attenuates the input voltage by a factor Ci/(Ci + Cg). In slave
mode, a minimum of 200 mV(RMS) is needed.
