XOUT

Oscillation

output

OUT

A crystal oscillator should be

connected between XIN and XOUT.

When using external clock input, the

external clock signal should be

connected to XIN, and XOUT should

be open.

VBUS

VBUS input

This should be connected directly to

the Vbus of the USB bus. The

connected or disconnected state of the

Vbus can be detected. If this pin is not

connected with Vbus of a USB bus,

connect 5V.

And in case of a host controller, please

fix to 5V too.

*This pin can’t supply vbus.
