2. Getting Started
2.1. SAM V71 Xplained Ultra Quick Start
Three steps to start exploring the Atmel SAM V71 Xplained Ultra:
1. Download Atmel Studio.
2. Launch Atmel Studio.
3. Connect a USB cable (Standard-A to Micro-B or Micro-AB) between the PC and the DEBUG USB
port on the kit.
When the Atmel SAM V71 Xplained Ultra is connected to your computer for the first time, the operating
system will do a driver software installation. The driver file supports both 32-bit and 64-bit versions of
Microsoft® Windows® XP, Windows Vista®, Windows 7, and Windows 8.
Once the kit is powered the green power LED will be lit and Atmel Studio will auto detect the kit and which
Xplained Pro extension board(s) are connected. Atmel Studio will present relevant information like
datasheets and kit documentation. The SAM V71 device is programmed and debugged by the on-board
Embedded Debugger and therefore no external programmer or debugger tool is needed.

3. Xplained Pro
SAM V71 Xplained Ultra implements several Xplained Pro standards like extension headers and
connectors, this chapter documents these standards.
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 that are integrated
with Atmel Studio, support data streaming and more. Xplained Pro MCU boards support a wide range of
Xplained Pro extension boards that 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 a
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 V71 Xplained Ultra 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 ATSAMV71Q21.
On SAM V71 Xplained Ultra, the SWD interface is connected between the EDBG and the
ATSAMV71Q21.
The Virtual COM Port is connected to a UART on the ATSAMV71Q21 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 ATSAMV71Q21 must match the settings given in the
terminal software.
Note: If not set automatically, data terminal ready (DTR) must be set in the terminal software.
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
ATSAMV71Q21 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 V71 Xplained Ultra; a power LED and a status LED. Table 3-1
EDBG LED Control on page 7 shows how the LEDs are controlled in different operation modes.
Table 3-1 EDBG LED Control
Operation Mode Power LED Status LED
Normal operation Power LED is lit when power is
applied to the board.
Activity indicator, LED flashes
when any communication
happens to the EDBG.
Bootloader mode (idle) The power LED and the status LED blinks simultaneously.
Bootloader mode (firmware
upgrade)
The power LED and the status LED blinks in an alternating pattern.
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. Table 3-2 Xplained Pro ID Chip Content on page 8
shows the data fields stored in the ID chip with example content.

3.3. Power Sources
The SAM V71 Xplained Ultra kit can be powered by several power sources listed in Table 3-3 Power

The kit will automatically detect which power sources are available and choose which one to use
according to the following priority:
1. External jack input.
2. External power.
3. Embedded Debugger USB.
4. 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 Table 3-4
Xplained Pro Standard Extension Header on page 9.
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.

3.4.2. Xplained Pro LCD Extension Connector
The LCD connector provides the ability to connect to display extensions that have a parallel interface.
The connector implements signals for a MCU parallel bus interface and a LCD controller interface as well
as signals for a touch controller. The connector pin-out definition is shown in Table 3-5 Xplained Pro LCD
Connector on page 10. Note that usually only one display interface is implemented, either the LCD
controller or the MCU bus interface.
A FPC/FFC connector with 50 pins and 0.5mm pitch is used for the LCD connector. The connector
XF2M-5015-1A from Omron is used on several Xplained Pro designs and can be used as a reference.
