3. Xplained Pro
Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The
platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated
with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data
streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards,
which are connected through a set of standardized headers and connectors. Each extension board has
an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board.
This information is used to present relevant user guides, application notes, datasheets, and example
code through Atmel Studio.
3.1. Embedded Debugger
The SAM D11 Xplained Pro contains the Atmel Embedded Debugger (EDBG) for on-board debugging.
The EDBG is a composite USB device of three interfaces; a debugger, Virtual COM Port, and a Data
Gateway Interface (DGI).
Together with Atmel Studio, the EDBG debugger interface can program and debug the ATSAMD11D14A.
On SAM D11 Xplained Pro, the SWD interface is connected between the EDBG and the
ATSAMD11D14A.
The Virtual COM Port is connected to a UART on the ATSAMD11D14A and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. Note that the settings on the ATSAMD11D14A must match the settings given in the
terminal software.
Info: The virtual COM port in the EDBG requires the terminal software to set the data terminal
ready (DTR) signal to enable the UART pins connected to the ATSAMD11D14A. If the DTR
signal is not enabled the UART pins on the EDBG is kept in high-z (tristate) rendering the COM
port unusable. The DTR signal is set automatically by some terminal software, but it may have
to be manually enabled in your terminal.
The DGI consists of several physical interfaces for communication with the host computer.
Communication over the interfaces is bidirectional. It can be used to send events and values from the
ATSAMD11D14A or as a generic printf-style data channel. Traffic over the interfaces can be timestamped
on the EDBG for more accurate tracing of events. Note that timestamping imposes an overhead that
reduces maximal throughput. Atmel Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs on SAM D11 Xplained Pro; a power LED and a status LED. The table
below shows how the LEDs are controlled in different operation modes.
Table 3-1. EDBG LED Control
Operation mode Power LED Status LED

For further documentation on the EDBG, see the EDBG User Guide.
3.2. Hardware Identification System
All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and some extra data.
When an Xplained Pro extension is connected to an Xplained Pro MCU 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. The table below shows the data fields stored in the ID
chip with example content.

3. Target USB.
Info: External power is required when 500mA from a USB connector is not enough to power
the board with possible extension boards. A connected USB device in a USB host application
might easily exceed this limit.
3.4. Xplained Pro Headers and Connectors
3.4.1. Xplained Pro Standard Extension Header
All Xplained Pro kits have one or more dual row, 20-pin, 100mil extension header. Xplained Pro MCU
boards have male headers, while Xplained Pro extensions have their female counterparts. Note that all
pins are not always connected. All connected pins follow the defined pin-out description in the table
below.
The extension headers can be used to connect a variety of Xplained Pro extensions to Xplained Pro MCU
boards or to access the pins of the target MCU on Xplained Pro MCU boards directly.

4.1.2. Current Measurement Header
An angled 1x2, 100mil pin-header marked with MCU current measurement is located at the upper edge of
the SAM D11 Xplained Pro. All power to the ATSAMD11D14A is routed through this header. To measure
the power consumption of the device remove the jumper and replace it with an ammeter.
Caution: Removing the jumper from the pin-header while the kit is powered may cause the
ATSAMD11D14A to be powered through its I/O pins. This may cause permanent damage to the
device.
4.2. Peripherals
4.2.1. Crystal
The SAM D11 Xplained Pro kit contain one crystal footprint that can be used for mounting a clock source
for the SAM D11 device. The I/O pins for the crystal are shared with the extension header, so two 0Ω
resistors (R311 and R312) must be removed before mounting a crystal on the footprint.

PA09 XOUT32
4.2.2. Mechanical Buttons
SAM D11 Xplained Pro contains two mechanical buttons. One button is the RESET button connected to
the SAM D11 reset line and the other is a generic user configurable button. When a button is pressed it
will drive the I/O line to GND.

4.2.4. Touch Buttons
There are two self capacitance buttons available on the SAM D11 Xplained Pro board that can be used
as I/O. These QTouch buttons are intended to be driven by the built-in Peripheral Touch Controller (PTC)
of the device.
Atmel SAM D11 Xplained Pro [USER GUIDE]
Atmel-42349B-SAM-D11-Xplained-Pro_User Guide-04/2016

0Ω resistors are added on the board to easily disconnect either the onboard touch buttons or the
connection to the extension header, as the I/O lines are shared between the two. These resistors can be
found on the back side of the board, marked "QTBTN1" and "QTBTN2" for disconnecting the touch
buttons, and "EXT-3" and "EXT-4" for disconnecting the lines to the extension header.
Table 4-5. QTouch Button Connections

PA03 QT BTN2
4.2.5. USB
The SAM D11 Xplained Pro has a Micro-USB connector for use with the SAM D11 USB module. To be
able to detect when a target USB cable is connected in self-powered mode, a GPIO is used to detect the
VBUS voltage on the connector.
Table 4-6. USB Connections
Pin on SAM D11 USB
PA27 VBUS Detection(1)
PA24 USB D-
PA25 USB D+
Note:
1. PA27 is shared between SPI SS to the EDBG and VBUS detect on target USB. This is
implemented so the pin can detect if VBUS is present when configured as input with no internal
pull. If VBUS is present, the level on the pin will be high. If VBUS is not present, the line is
externally pulled low. It will not be possible to detect this if the EDBG SPI DGI interface is enabled
from Atmel Data Visualizer.
4.3. Embedded Debugger Implementation
SAM D11 Xplained Pro contains an Embedded Debugger (EDBG) that can be used to program and
debug the ATSAMD11D14A using Serial Wire Debug (SWD). The Embedded Debugger also include a
Virtual Com port interface over UART, an Atmel Data Gateway Interface over SPI, and TWI and it
includes four of the SAM D11 GPIOs. Atmel Studio can be used as a front end for the Embedded
Debugger.
4.3.1. Serial Wire Debug
The Serial Wire Debug (SWD) use two pins to communicate with the target. For further information on
how to use the programming and debugging capabilities of the EDBG, see Embedded Debugger.

4.3.2. Virtual COM Port
The Embedded Debugger acts as a Virtual Com Port gateway by using one of the ATSAMD11D14A
UARTs. For further information on how to use the Virtual COM port see Embedded Debugger.

4.3.3. Atmel Data Gateway Interface
The Embedded Debugger features an Atmel Data Gateway Interface (DGI) by using either a SPI or I²C
port. The DGI can be used to send a variety of data from the SAM D11 to the host PC. For further
information on how to use the DGI interface see Embedded Debugger.

Note:
1. PA27 is shared between SPI SS to the EDBG and VBUS detect on target USB. This is
implemented so the pin can detect if VBUS is present when configured as input with no internal
pull. If VBUS is present, the level on the pin will be high. If VBUS is not present, the line is
externally pulled low. It will not be possible to detect this if the EDBG SPI DGI interface is enabled
from Atmel Data Visualizer.

Four GPIO lines are connected to the Embedded Debugger. The EDBG can monitor these lines and time
stamp pin value changes. This makes it possible to accurately time stamp events in the SAM D11
application code. For further information on how to configure and use the GPIO monitoring features see

If contention with the on-board EDBG occur, power the Xplained Pro board from another input
like the external power header or from the target USB. Physically removing the connection
between the EDBG and the debug header by removing 0Ω resistors, where available, or cutting
the tracks to the EDBG can also be done.

6. Hardware Revision and Known Issues
6.1. Identifying Product ID and Revision
The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel
Studio or by looking at the sticker on the bottom side of the PCB.
By connecting an Xplained Pro MCU 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 Kit's 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 product identifier for SAM D11 Xplained Pro is A09-2178.
6.2. Revision 3
