Getting Started
2.
Getting Started
The ATWINC3400-XPRO has been designed to be connected to an Xplained Pro extension header marked as
EXT1. However, it is compatible with all Xplained Pro extension headers. Refer to the pin-out of your Xplained Pro
evaluation kit to find out which Xplained Pro extension headers can be used.
2.1
Xplained Pro Quick Start
Steps to start exploring the Xplained Pro platform:
1. Download and install Microchip Studio/MPLAB® X.
2. Launch Microchip Studio/MPLAB® X.
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 Microchip Studio/MPLAB® X
automatically detects the specific Xplained Pro MCU and extension board(s) that are connected. The landing page
of the kit in the Microchip Studio has an option to launch the Advanced Software Framework (ASF) and the Atmel
START example application codes for the kit. The target device is programmed and debugged by the on-board
embedded debugger and, therefore, no external programmer or debugger tool is required.

Xplained Pro
Xplained Pro is an evaluation platform containing a series of microcontroller boards (evaluation kits) and extension
boards. Microchip Studio/MPLAB® X is used to program and debug the microcontrollers on these boards. Microchip
Studio includes Advanced Software Framework (ASF) and Atmel START which has drivers, demo code, and Data
Visualizer that 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 the Microchip Studio/MPLAB® X. The following table
shows the data fields stored in the ID chip with example content.

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. The following table provides the pin
description of all the connected pins.
Info: Not all pins are always connected to 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.

Power Measurement Header
Current measurement header (J102) can be used to measure the total current consumed by the ATWINC3400MR210CA module using a voltmeter. To measure the total current consumption of the module, remove the jumper
from J102 and connect a voltmeter across its pins. A 1Ω resistor available on board across the jumper gives a 1:1
relationship between voltage drop and current consumption.

•
Microchip products meet the specifications contained in their particular Microchip Data Sheet.
Microchip believes that its family of products is secure when used in the intended manner and under normal
conditions.
There are dishonest and possibly illegal methods being used in attempts to breach the code protection features
of the Microchip devices. We believe that these methods require using the Microchip products in a manner
outside the operating specifications contained in Microchip’s Data Sheets. Attempts to breach these code
protection features, most likely, cannot be accomplished without violating Microchip’s intellectual property rights.
Microchip is willing to work with any customer who is concerned about the integrity of its code.
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of its code. Code
protection does not mean that we are guaranteeing the product is “unbreakable.” Code protection is constantly
evolving. We at Microchip are committed to continuously improving the code protection features of our products.
Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act.
If such acts allow unauthorized access to your software or other copyrighted work, you may have a right to sue
