VDDA33_USB

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 .

USBPH

VDDA33_USB

USB D- (differential signal pair)

Note: If the USB peripheral is not used at all in the

application, this pin should be connected to VSS.

VDDA33_USB

PWR

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.

VSSA33_USB

GND

3.3-V USB ground

Note: If the USB peripheral is not used at all in the

application, this pin should be connected to VSS.

VDDA12LDO_USB

PWR

Output

For proper device operation, even if the USB

peripheral is not used, a 0.22

µF capacitor must be

connected as close as possible to the package, and

the capacitor mst be connected to VSSA.

VDDA18_USB

PWR

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.

VSSA18_USB

GND

1.8-V USB ground

Note: If the USB peripheral is not used at all in the

application, this pin should be connected to VSS.

USB_ID

USBPH

VDDA33_USB

USB operating mode identification pin.

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

A I/O

USBPH

USB_VBUS

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

DM368 perspective, when operating as a Host, it

ensures that the external power supply that the

DM368 has sourced is within the required voltage

level (

>= 4.4V) and when DM368 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 DM368 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.
