USB D+ (differential signal pair)
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to 3.3V .
USB D- (differential signal pair)
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to V_SS.
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.
3.3-V USB ground
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to V_SS.
For proper device operation, even if the USB
peripheral is not used, a 0.22µF capacitor must be
connected as close as possible to the package, and
the capacitor mst be connected to V_SSA.

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.
1.8-V USB ground
Note: If the USB peripheral is not used at all in the
application, this pin should be connected to V_SS.
USB operating mode identification pin.
For device mode operation only, pull up this pin to
V_DD with a 1.5K ohm resistor.
For host mode operation only, pull down this pin to
ground (V_SS) 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.
This pin is used by the USB Controller to detect a
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 V_SS.
