2. Getting Started
2.1. Three Steps to Start Exploring the Atmel Xplained Pro Platform
1. Download and install Atmel Studio.
2. Launch Atmel Studio.
3. Connect the SMARTCARD Xplained Pro to the Xplained Pro MCU board and connect a USB cable
to the DEBUG USB port on the Xplained Pro MCU board.
2.2. Connecting the SMARTCARD Xplained Pro to the Xplained Pro MCU Board
SMARTCARD Xplained Pro is designed to be connected to the Xplained Pro header marked EXT3. It is
compatible with EXT2 as well. Refer to the pin-out of your Xplained Pro evaluation kit to find out which
Xplained Pro EXT headers that can be used.
Once the Xplained Pro MCU board is powered, the green power LED will be lit and Atmel Studio will autodetect which Xplained Pro MCU and extension board(s) are connected. Atmel Studio will present relevant
information like datasheets and kit documentation. The kit landing page in Atmel Studio also have the
option to launch Atmel Software Framework (ASF) example applications for the kit. The target device is
programmed and debugged by the on-board Embedded Debugger. No external programmer or debugger
tool is needed.

3. Xplained Pro
Xplained Pro is an evaluation platform that provides the complete Atmel microcontroller and SoC RF
experience.
The platform consists of :
• Microcontroller (MCU) and RF evaluation kits
• Support a wide range of extension boards
• Atmel Software Framework (ASF) drivers and demo code integrated with Atmel Studio
• User guides, application notes, datasheets, and example code through Atmel Studio Xplained Pro
MCU and extension boards can be purchased in the Atmel Web Store
3.1. Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204A CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension board is connected to an Xplained Pro board the information is read and
sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information,
code examples, and links to relevant documents. Table 3.1 "Xplained Pro ID Chip Content" shows the
data fields stored in the ID chip with example content.

3.2. Standard Headers and Connectors
3.2.1. Xplained Pro Standard Extension Header
All Xplained Pro evaluation kits have one or more dual row, 20-pin, 100mil extension headers. Xplained
Pro boards have male headers while Xplained Pro extension boards have their female counterparts. Note
that all pins are not always connected. However, all the connected pins follow the defined pin-out
described in Table 3.2 Xplained Pro Extension Header . The extension headers can be used to connect a
wide variety of Xplained Pro extensions to Xplained Pro boards and to access the pins of the target MCU
on Xplained Pro board directly.

5. Hardware Revision History and Known Issues
5.1. Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; through Atmel
Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro board to a computer with Atmel Studio running, an information window will
pop up. The first six digits of the serial number, which is listed under kit details, contain the product
identifier and revision. Information about connected Xplained Pro extension boards will also appear in the
Atmel Kits window.
The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the
identifier and revision in plain text as A09-nnnn\rr where nnnn is the identifier and rr is the revision.
Boards with limited space have a sticker with only a QR-code which contains a serial number string.
The serial number string has the following format:
"nnnnrrssssssssss"
n = product identifier
r = revision
s = serial number
The kit identifier for SMARTCARD Xplained Pro is 2593.
