Atmel SAME70-XPLD [USER GUIDE] 6 Atmel-44050A-SAME70-XPLD_User Guide-12/2015 3. Xplained Pro 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, which are integrated with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards, which 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 an 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 SAME70-XPLD 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 can program and debug the ATSAME70Q21. On the SAME70- XPLD, 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 terminal software. It offers variable baud rate, parity, and stop bit settings. Note that the settings on the ATSAME70Q21 must match the settings applied 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 are 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 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. 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. The table below shows the data fields stored in the ID chip with example content.

3.3. Power Sources The SAME70-XPLD kit can be powered by several power sources listed in the table below.
Warning: The 3.3V power domain is locally generated and must never be supplied from external sources or this would damage the on-board regulators.
Table 3-2 SAME70-XPLD Power Sources
Power input Voltage requirements Connector marking Embedded debugger USB 4.4V to 5.25V (USB spec.) DEBUG USB Target USB 4.4V to 5.25V (USB spec.) TARGET USB Arduino connector 5.0V typically J501 (pin 5)
In case of USB power sources, the board automatically detects and switches to the available one. If the two are present (which is no problem whatsoever) the following priority applies: 1. Target USB (J302 connector) 2. Embedded Debugger USB (J900 connector)
Info: USB sources supposedly provide a maximum current of 500mA. Calculate the power budget of your system, there is a possiblity this could be not enough if your SAME70-XPLD also connects to power demanding extension boards.
The optional 5Vcc power source from the Arduino connector J501 is connected in parallel to the USB power switching system, hence the following warning:
Warning: do not power the board form the Arduino shield (J501) when either of the two USB sources are connected. Doing so could damage the board and potentially also damage the USB port of your PC.
3.4. 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 the table below.
Atmel SAME70-XPLD [USER GUIDE] 8 Atmel-44050A-SAME70-XPLD_User Guide-12/2015 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.

4.3.2. Arduino Connectors Five 8-pin, one 10-pin, one 2×3-pin and one 2×18-pin headers footprints (J500 to J507) are implemented on the board to enable the addition of "Arduino shields" extension cards. These accessory boards are various and widely available on the market, often custom developed. Due to the PIO multiplexing of the ATSAME70Q21, various peripheral signals may be connected to each pin. These connectors are mechanically (location and footprint) compatible with the Arduino R3 shields.
Important: As the SAM E70 signals have a voltage level of 3.3V, 5V level shields cannot properly function with SAME70-XPLD.
In addition to its standard IO functionality, the SAM E70 microcontroller can provide alternate functions to external IO lines available on the J500 to J507 headers. These alternate functions are:

Caution: Like the Arduino Due, SAME70-XPLD runs at 3.3V and the maximum voltage that the I/O pins can tolerate is 3.3V, connecting higher voltages e.g. 5V to those I/O pin could damage the board.
Important: not all pins of the shield connectors are necessarily connected to an I/O of the ATSAME70Q21. Each shield should be checked for compatibility against the SAME70-XPLD schematics before it is purchased and connected.
4.3.2.1. J500 Header J500 is a 10-pin header with 2.54mm pitch. It is not populated by default and can be used to connect to Arduino Shields. It includes PWM, Timer Counter and I2C interface signals and analog reference.

4.3.5. Current Measurement Header (VCC_MCU_P3V3 ) A 100mil pin-header marked "J203" is located at the upper edge of the SAME70-XPLD. All the power going to the ATSAME70Q21 is routed through this header. To measure the power consumption of the device, remove the jumper and replace it with an ammeter.
Figure 4-14 VCC_MCU_P3V3 Connector Placement J203
J203
Caution: Removing the jumper from the pin-header while the board is connected to otherwise powered extension boards or systems may cause the ATSAME70Q21 to be powered through its I/O pins. This could cause permanent damage to the device.
4.3.6. VDDCORE Current Measurement A 100mil pin-header marked "J201" is located at the upper edge of the SAME70-XPLD board. It is not mounted by default and is replaced by a shunt trace between the two pads of the connector. All power to VDDCORE of the ATSAME70Q21 is routed through this header. To measure the power consumption of VDDCORE, cut the shunt trace between the two points, mount a header or solder wires and connect an ammeter.

Atmel SAME70-XPLD [USER GUIDE] 28 Atmel-44050A-SAME70-XPLD_User Guide-12/2015 Caution: Leaving J201 open while the main power source is present is to be avoided. This would feed all power pins of the ATSAME70Q21 except VDDCORE, which may cause permanent damage to the device.
4.3.7. Chip Erase Header The chip erase header J200 is connected to the SAM E70 erase pin (PB12) and the main 3.3V. To erase the contents of the SAM E70 flash memory, set a jumper on J200 and turn the power supply on. The jumper can be removed soon after the power is on (flash erasing takes only 200ms). Using the chip erase jumper is the only way to erase a chip with the security bit set.

4.4. Peripherals
4.4.1. Clock Circuitry The SAME70-XPLD board features three clock sources: • Two crystals for the ATSAME70Q21 processor • One crystal oscillator for the Ethernet MII/RMII chip The crystals of the ATSAME70Q21 have cut-straps next to them that can be used to measure the oscillator safety factor. This is done by cutting the strap and adding a resistor across the strap. Information about oscillator allowance and safety factor can be found in the application note AVR4100; information about clock calibration and compensation can be found in the application note AT03155.

4.4.6. Ethernet The ATSAME70Q21 has a built-in 10/100 Mbps Ethernet IEEE 802.3 compatible MAC with RMII interface. The SAME70-XPLD connects the MAC to a Micrel KSZ8081RNACA RMII physical-layer transceiver (PHY), which is connected to one RJ45 Ethernet connector. A unique EUI-48™ address is available on every SAME70-XPLD through the on-board AT24MAC402, the EUI-48 address can be used as a MAC address for the KSZ8081RNACA. The address is also programmed into the on-board EDBG. Table 4-19 KSZ8081RNACA Connections on page 35 lists all pins connected from the SAM E70 to the Ethernet PHY.
Info: Several of the Ethernet signals are shared with the trace connector and thus there is no Ethernet support if trace is used in an application.
