2. Xplained Pro Getting Started
2.1 Xplained Pro Quick Start
Steps to start exploring the Xplained Pro platform:
1. Download and install Atmel Studio.
2. Launch Atmel Studio.
3. Connect the Debug USB port on the evaluation kit to the computer using a USB cable (Standard-A
to Micro-B or Micro-AB).
When the Xplained Pro MCU kit is connected to the computer for the first time, the operating system
installs the driver software automatically. This driver supports 32-bit and 64-bit versions of Microsoft®
Windows® XP, Windows Vista®, Windows 7, Windows 8, Windows 10, and Windows Server 2012.
When the Xplained Pro MCU board is powered, the power LED (green) glows and the Atmel Studio
automatically detects the specific Xplained Pro MCU and extension board(s) that are connected. The
landing page of the kit in the Atmel Studio has an option to launch the Atmel Software Framework (ASF)
and the Atmel START example application codes for the kit. The SAM B device is programmed and
debugged by the on-board embedded debugger and therefore no external programmer or debugger tool
is required.
2.2 Design Documentation and Relevant Links
The following list contains links to the most relevant documents and software for the SAM B11ZR
Xplained Pro.
•Xplained products - Xplained evaluation kits are a series of easy-to-use evaluation kits for
microcontrollers and other products. For low pin count devices, the Xplained Nano series provides
a minimalistic solution with access to all I/O pins of the target microcontroller. Xplained Mini kits are
for medium pin count devices and adds Arduino Uno compatible header footprint and a prototyping
area. Xplained Pro kits are for medium to high pin count devices, and feature advanced debugging
and standardized extensions for peripheral functions. All these kits have on board programmers/
debuggers which creates a set of low-cost boards for evaluation and demonstration of features and
capabilities of different products.
•Atmel Studio - Atmel Studio presents Free Atmel IDE for development of C/C++ and assembler
code for microcontrollers and relevant documentation.

3. Xplained Pro
3.1 Xplained Pro
Xplained Pro is an evaluation platform which contains a series of microcontroller boards (evaluation kits)
and extension boards. Atmel Studio is used to program and debug the microcontrollers on these boards.
Atmel Studio includes Advanced Software Framework (ASF) and Atmel START, which has drivers and
demo code, and Data Visualizer, which supports data streaming and advanced debugging. Xplained Pro
evaluation kits can be connected to a wide range of Xplained Pro extension boards through standardized
headers and connectors. Xplained Pro extension boards have identification (ID) chips to uniquely identify
which boards are connected to the Xplained Pro evaluation kits.
3.2 Embedded Debugger
The SAM B11ZR Xplained Pro contains an Embedded Debugger (EDBG) for on-board debugging. The
EDBG is a USB composite device with the following interfaces:
• Debugger
• Virtual COM Port
• Data Gateway Interface (DGI)
The EDBG can program and debug the ATSAMB11ZR with the help of Atmel Studio. The SWD interface
is connected between the EDBG and the ATSAMB11ZR on the SAM B11ZR Xplained Pro.
The Virtual COM Port is connected to a UART on the ATSAMB11ZR and provides an easy way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and
stop bit settings. The settings on the ATSAMB11ZR 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 ATSAMB11ZR. If the
DTR signal is not enabled, the UART pins on the EDBG are kept in tri-state (high-z) to render
the COM Port not usable. The DTR signal is automatically set by some terminal software, but it
may have to be manually enabled in your terminal.
The DGI consists of several physical interfaces for bidirectional communication with the host computer.
Communication over the interfaces is bidirectional. It can be used to send event values, and data from
the ATSAMB11ZR. Traffic over the interfaces can be timestamped by the EDBG for more accurate tracing
of events, but timestamping reduces the maximal data throughput. The Data Visualizer is used to send
and receive data through DGI.
The EDBG controls two LEDs on the SAM B11ZR Xplained Pro, a power LED and a status LED. The
following table provides details on how the LEDs are controlled in different operation modes.

3.3 Xplained Pro Analog Module
3.3.1 Overview
The Xplained Pro Analog Module (XAM) extends the embedded debugger with high dynamic range
current measurement. This enables power profiling of the target system.

The XAM consists of:
• Calibration circuitry
• Voltage reference circuitry
• Analog front-end:
– Shunt resistors with a range selection switch
– Pre-amplifier
– Two active filters with gain
• Control MCU
ATSAMB11ZR

– Analog-to-Digital Converter
– Signal processing
– Control/communication interface to the EDBG
The current measurement front-end is a high side shunt measurement with a pre-amplifier and a second
active filter stage with gain as shown in Figure 3-1. The wide dynamic range is achieved by four
measurement ranges, which are defined by two shunt resistors and the two parallel second stage active
filters with gain.
3.3.2 Sample Rate
The raw sampling rate of the XAM is up to 250 kHz and with the default averaging configuration (average
of 16 samples), the actual output of the XAM is 16.67 ksps.
Info: The XAM output sample rate is not an integer fraction of the raw sampling.
3.3.3 Measurement Ranges and Accuracy
The XAM has four measurement ranges. These are defined by two shunt resistors and two gain stages.
Table 3-2. XAM Measurement Ranges and Accuracy
Measurement
Range
Hardware Resolution Accuracy Comments
Range 1 Low current shunt and
high gain stage
20 nA 1 LSB ±1% Accuracy will decrease below
1 μA. Typical accuracy for
300 nA is 1 LSB ±10%.
Range 2 Low current shunt and
low gain stage
150 nA 1 LSB ±1%
Range 3 High current shunt and
high gain stage
10 μA 1 LSB ±1%
Range 4 High current shunt and
low gain stage
100 μA 1 LSB ±1% Accuracy will decrease above
100 mA. Typical accuracy is
1 LSB ±5% at 400 mA.
Maximum current is 400 mA.
The ranges are automatically switched by the XAM to achieve the best measurement results and the
currently active range is visualized in the Data Visualizer front-end tool. The maximum voltage drop over
the shunt resistor is 100 mV, and the XAM switches the range automatically before reaching this limit.
3.4 Hardware Identification System
All Xplained Pro extension boards come with an identification chip (ATSHA204A CryptoAuthentication™
chip) to uniquely identify the boards that are connected to the Xplained Pro evaluation kit. 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 evaluation kit, the information is read and sent to the
Atmel Studio. The following table shows the data fields stored in the ID chip with example content.

Battery header is another power input, refer to Battery Header.
The kit will automatically detect which power sources are available and choose which one to use
according to the following priority:
1. External power.
2. Embedded Debugger USB.
Note: The selection for the supply of the Target MCU has a separate connector. The above priority
selects which supply is used to power the EDBG and the VCC_P3V3_CON.
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.

3.6 Xplained Pro Headers and Connectors
3.6.1 Xplained Pro Standard Extension Header
All Xplained Pro kits have many dual row, 20-pin, 100-mil extension headers. The Xplained Pro MCU
boards have male headers, while the Xplained Pro extensions have their female counterparts. All
connected pins follow the defined pin description in the table.
