5.5 USB Connectivity
Users can connect to the PIC32 USB microcontroller using any one of the following modes:
• Host mode : If connecting the device to the Type-A/B Micro connector, an adapter is required. Using
this method, a maximum of 400 mA can be supplied from the debug USB port to the host port. If a
full 500 mA supply is needed, an external supply must be connected to the application board.
• Device mode : Connect the SAM E70 to the target USB Micro-A/B port using a USB cable. This is
enough to power the board as a device. If programming and debugging is required, connect the
Debug USB Micro-A/B port. The other end of the cable must have a Type-A connector, to connect it
to a USB host.
• On-The-Go (OTG) mode : Connect the starter kit to the OTG device by using an OTG Micro-A/B
cable to the Micro-A/B port.
There is a 1x3, 100mil pin-header marked VBUS on the kit. The PB08 pin on the SAM E70 can be
connected to the LED2 or to the target USB VBUS DETECT signal by placing a jumper between pin 1
and pin 2, or pin 2 and pin 3 on this pin-header. The USB VBUS DETECT is the target USB voltage
divided by 1.64. When connected to the PB08 pin the signal can be used to detect power on the target
USB connector.

2 PB08 Pin and Port to microcontroller
3 VBUS_ Detect VBUS Detect, used to detect when a device cable (micro-B) is plugged
into the SAM E70
The SAM E70 Xplained Ultra has a Micro-USB connector to use with the SAM E70 USB module labeled
as TARGET USB on the kit. In USB Host mode, the VBUS voltage is provided by the kit, and must be
enabled by setting the VBUS Host Enable pin to low. When a USB OTG cable is plugged in, it will
automatically trigger the power supply.
