3.3-V USB analog power supply
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to 3.3V.

PWR
Output
For proper device operation, even if the USB
peripheral is not used, a 0.22
F capacitor must be
connected as close as possible to the package, and
the capacitor mst be connected to VSSA.
VDDA18_USB

1.8-V USB analog power supply
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to 1.8V.

VDDA33_USB
USB operating mode identification pin.
Y
For device mode operation only, pull up this pin to
VDD with a 1.5K ohm resistor.
For host mode operation only, pull down this pin to
ground (VSS) with a 1.5K ohm resistor.
If using an OTG or mini-USB connector, this pin will
be set properly via the cable/connector configuration.
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to 3.3V.
USB_VBUS
N2
A I/O
USBPH
USB_VBUS
This pin is used by the USB Controller to detect a
Y
presence of 5V power (4.4V is the threshold) on the
USB_VBUS line for normal operation. This power is
sourced by the USB Component that is assuming the
role of a Host. In other words, the power on the
USB_VBUS line is not sourced by the Device. From
DM365 perspective, when operating as a Host, it
ensures that the external power supply that the
DM365 has sourced is within the required voltage
level (
>= 4.4V) and when DM365 is operating as a
Device, the presence of a 5V power on the VBUS
Line is used to signify the presence of an external
Host.
Note 1: When the DM365 is operating as a Device, it
uses the power on the USB_VBUS line to power up
its internal pull-up resistor on the D+ line.
Note2: If the USB peripheral is not used at all in the
application, this pin should be connected to VSS.
