Powering the Atmel-ICE

The Atmel-ICE is powered by the USB bus voltage. It requires less than 100mA to operate, and can therefore
be powered through a USB hub. The power LED will illuminate when the unit is plugged in. When not
connected in an active programming or debugging session, the unit will enter low-power consumption mode to
preserve your computer's battery. The Atmel-ICE cannot be powered down - it should be unplugged when not
in use.

Connecting to the Host Computer

The Atmel-ICE communicates primarily using a standard HID interface, and does not require a special driver on
the host computer. To use the advanced data gateway functionality of the Atmel-ICE, be sure to install the USB
driver on the host computer. This is done automatically when installing the front-end software provided free by
Atmel. See www.atmel.com
The Atmel-ICE must be connected to an available USB port on the host computer using the USB cable
provided, or suitable USB certified micro cable. The Atmel-ICE contains a USB 2.0 compliant controller, and
can operate in both full-speed and high-speed modes. For best results, connect the Atmel-ICE directly to a
USB 2.0 compliant high-speed hub on the host computer using the cable provided.
