2.1 Electrostatic Warning
The AT91SAM9XE-EK evaluation board is shipped in protective anti-static packaging. The board must
not be subjected to high electrostatic potentials. A grounding strap or similar protective device should be
worn when handling the board. Avoid touching the component pins or any other metallic element.
2.2 Requirements
In order to set up the AT91SAM9XE-EK evaluation board, the following items are needed:
the AT91SAM9XE-EK evaluation board itself.
AC/DC power adapter (5V at 2A), 2.1 mm by 5.5 mm

2.4 Powering Up the Board
The AT91SAM9XE-EK requires 5V DC (±5%). DC power is supplied to the board via the 2.1 mm by 5.5
mm socket J1. Coaxial plug center positive standard.
2.5 Backup Power Supply
The user has the possibility to plug a battery (3V Lithium Battery CR1225 or equivalent) in order to permanently power the backup part of the device. In this case, J10 configuration must be set in position 1, 2.
Refer to Section 4.1.
2.6 Getting Started
The AT91SAM9XE-EK evaluation board is delivered with a CD-ROM containing all necessary information and step-by-step procedures for working with the most common development toolchains. Please
refer to this CD-ROM, or to the AT91 web site, http://www.atmel.com/products/AT91/, for the most up-todate information on getting started with the AT91SAM9XE-EK.
