2. 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.
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 QT7 Xplained Pro device is programmed
and debugged by the on-board embedded debugger and therefore no external programmer or debugger
tool is required.
2.2 Design Document and Relevant Links
Xplained Products: Xplained evaluation kits are a series of easy-to-use evaluation kits for
Microchip microcontrollers and other Microchip products.
Xplained Nano – used for low pin count devices and provides a minimalistic solution with
access to all I/O pins of the target microcontroller.
Xplained Mini – used for medium pin count devices and adds an Arduino Uno compatible
header footprint and a prototyping area.
Xplained Pro – used for medium to high pin count devices that feature advanced debugging
and standardized extensions for peripheral functions.
Note:  All the above kits have on-board programmers/debuggers, which creates a set of low-cost
boards for evaluation and demonstration of features and capabilities of different Microchip products.
Atmel Start: This tool will help you select and configure software components and tailor your
embedded application in a usable and optimized manner.
Atmel Studio: Free Atmel IDE for development of C/C++ and assembler code for Atmel
microcontrollers.
Atmel Data Visualizer: Atmel Data Visualizer is a program used for processing and visualizing
data. Data Visualizer can receive data from various sources such as the Embedded Debugger Data
Gateway Interface found on Xplained Pro boards and COM ports.
Design Documentation: Package containing CAD source, schematics, BOM, assembly drawings,
3D plots, layer plots, etc.

3. Xplained Pro
The Xplained Pro is an evaluation platform that 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.
3.1 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 Atmel
Studio. The following table shows the data fields stored in the ID chip with example content.
Table 3-1. Xplained Pro ID Chip Content
Data Field Data Type Example Content
Manufacturer ASCII string Microchip'\0'
Product name ASCII string Segment LCD1 Xplained Pro'\0'
Product revision ASCII string 02'\0'
Product serial number ASCII string 1774020200000010’\0’
Minimum voltage [mV] uint16_t 3000
Maximum voltage [mV] uint16_t 3600
Maximum current [mA] uint16_t 30
3.2 Xplained Pro Standard Connectors
3.2.1 Xplained Pro Standard Extension Headers
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. The
following table provides the pin description of all the connected pins.
Info:  Not all pins are always connected on all extension headers.
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 microcontroller on the Xplained Pro boards.
