1. Getting Started
SAM E70 Xplained Ultra Evaluation Quick Start
Follow these steps to explore the Atmel SAM E70 Xplained Ultra evaluation kit:
1. Download and install MPLAB X.
2. Launch MPLAB X.
3. Install MPLAB Harmony 3™.
When Microchip SAM E70 Xplained Ultra is connected to the computer for the first time, the operating
system will install a driver software. The driver file supports both 32-bit and 64-bit versions of Microsoft®
Windows® XP/ Vista /7/8/10.
Once the kit is powered, the green power LED will be lit and MPLAB X will auto-detect the kit and identify
which Xplained Pro extension boards are connected. MPLAB X will provide relevant information like data
sheets and kit documentation. The SAM E70 device is programmed and debugged by the on-board
Embedded Debugger, hence no external programmer or debugger tool is needed.

2. Xplained Ultra
The SAM E70 Xplained Ultra implements several Xplained Pro standards like extension headers and
connectors. Xplained Pro is an evaluation platform that provides a full Microchip microcontroller
experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards that
are integrated with the Microchip MPLAB IDE that supports data streaming. The Xplained Pro MCU
boards support a wide range of Xplained Pro extension boards, such as audio DACs/CODECs, Ethernet
PHYs, graphics cards, and mikroBUS™ 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, data sheets, and example code through MPLAB X.

3. Embedded Debugger
The SAM E70 Xplained Ultra contains Microchip Embedded Debugger (EDBG) for on-board debugging.
The EDBG is a composite USB device, which is based on the following interfaces:
• Debugger
• Virtual COM Port
• Data Gateway Interface (DGI)
Together with the Microchip MPLAB IDE, the EDBG debugger interface can program and debug the
ATSAME70Q21. On the SAM E70 Xplained Ultra, the SWD interface is connected between the EDBG
and the ATSAME70Q21.
The Virtual COM Port is connected to a UART on the ATSAME70Q21 and provides an easy way to
communicate with the target application through the terminal software. It offers variable baud rate, parity,
and Stop bit settings. The settings on the ATSAME70Q21 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
ATSAME70Q21, or as a generic printf-style data channel. Traffic over the interfaces can be timestamped
on the EDBG for accurate tracing of events. Note that timestamping imposes an overhead that reduces
maximal throughput. The Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs on SAM E70 Xplained Ultra: a power LED and a status LED.
The following table describes how the LEDs are controlled in different operation modes.
Table 3-1. EDBG LED Control
Operation Mode Power LED Status LED
Normal operation The 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.
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.
The power LED and the status LED

For additional information on EDBG, refer to the EDBG User Guide.
3.1 Hardware Identification System
All Xplained Pro-compatible extension boards have an Microchip ATSHA204 CryptoAuthentication™ chip
mounted. This chip contains information that identifies the extension with its name and data. When an
Xplained Pro extension is connected to an Xplained Pro MCU board, the information is read and sent to
the MPLAB X IDE. The Microchip kits extension, installed with MPLAB X, provides relevant information,
such as code examples, and links to relevant documents. The following table provides the data fields
stored in the ID chip with content examples.
