3. Getting Started

3.1 Xplained Pro Quick Start

Steps to start exploring the Xplained Pro platform:

1. Download and install Atmel Studio.

2. Launch Atmel Studio.

3. Connect the DEBUG USB port on the evaluation kit to the computer using a USB cable (StandardA to Micro-B or Micro-AB).

The operating system installs the driver software automatically the first time the Xplained Pro evaluation kit is connected to a PC. 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 Atmel Studio automatically detects the specific Xplained Pro MCU and extension board(s) that are connected. The kit landing page in Atmel Studio comes with an option to launch Atmel Software Framework (ASF) and Atmel START example application codes for the kit. The SAM E54 device is programmed and debugged by the on-board Embedded Debugger and therefore no external programmer or debugger tool is required.

4. Xplained Pro

Xplained Pro is an evaluation platform which 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 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.

4.1 Embedded Debugger

The SAM E54 Xplained Pro contains an Embedded Debugger (EDBG) for on-board debugging. The EDBG is a USB composite device with the following interfaces:

• Debugger

• Virtual COM Port

• Data Gateway Interface (DGI)

The EDBG can program and debug the ATSAME54P20A with the help of Atmel Studio. The SWD interface is connected between the EDBG and the ATSAME54P20A on the SAM E54 Xplained Pro.

SAM E54 Xplained Pro

The Virtual COM Port is connected to a UART on the ATSAME54P20A and provides an easy way to communicate with the target application through terminal software. It offers variable baud rate, parity, and stop bit settings. The settings on the ATSAME54P20A must match the settings given in the terminal software.

Info: The Virtual COM Port in the EDBG requires the terminal software to set the Data Terminal Ready (DTR) signal to enable the UART pins connected to the ATSAME54P20A. If the DTR signal is not enabled, the UART pins on the EDBG are kept in tri-state (high-z) to render the COM Port not usable. The DTR signal is automatically set by some terminal software, but it may have to be manually enabled in your terminal.

The DGI consists of several physical interfaces for bidirectional communication with the host computer. Communication over the interfaces is bidirectional. It can be used to send event values, and data from the ATSAME54P20A. Traffic over the interfaces can be timestamped by the EDBG for more accurate tracing of events, but timestamping reduces the maximal data throughput. The Data Visualizer is used to send and receive data through DGI.

The EDBG controls two LEDs on the SAM E54 Xplained Pro: a power LED and a status LED. The table below shows how the LEDs are controlled in different operation modes.

– Control/communication interface to the EDBG

The current measurement front-end is a high side shunt measurement with a pre-amplifier and a second active filter stage with gain as shown in Figure 4-1. The wide dynamic range is achieved by four measurement ranges, which are defined by two shunt resistors and the two parallel second stage active filters with gain.

4.2.2 EDBG Interface

The XAM is connected to the EDBG with the following interfaces:

• I2C: This is used to control and configure the XAM.

• SPI: Current measurement data is streamed to the EDBG via this interface. This is a unidirectional channel from the XAM to the EDBG.

• SWD: The MCU in the XAM is programmed via SWD from the EDBG.

• Clock sync: Signal used to synchronize ADC measurements with the EDBG.

• Reference clock: Reference clock for the XAM.

4.2.3 Sample Rate

The raw sampling rate of the XAM is up to 250 kHz and with the default averaging configuration (average of 16 samples), the actual output of the XAM is 16.67 ksps.

SAM E54 Xplained Pro

Info: The XAM output sample rate is not an integer fraction of the raw sampling.

4.2.4 Measurement Ranges and Accuracy

The XAM has four measurement ranges. These are defined by two shunt resistors and two gain stages.

Range 2 Low current shunt and

above 100 mA. Typical accuracy is 1 LSB ±5% at 400 mA. Maximum current is 400 mA.

DS70005321A-page 11

The ranges are automatically switched by the XAM to achieve the best measurement results and the currently active range is visualized in the Data Visualizer front-end tool. The maximum voltage drop over the shunt resistor is 100 mV, and the XAM switches the range automatically before reaching this limit.

4.3 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.

5.2.3 PCC Camera Connector

A 2x10, 100-mil pin-header footprint for camera connector is implemented to give access to the SAM E54's Parallel Capture Controller (PCC). The footprint is compatible with common ArduCAM modules.

Info: The PCC connector is not functional by default due to shared functionality with Ethernet, QTouch, SD Card, EXT1, and EXT2. If using the PCC, you will partially or fully loose the ability to use these other functions.

Info: Soldering is required to get the PCC functional. Refer to Kit Modifications for details on modifications needed.

DS70005321A-page 19

SAM E54 Xplained Pro

Tip: The DEN1 and DEN2 signals connected to VSYNC and HYSNC on the PCC camera

connector are used to tell the PCC module when there is valid data to sample on the data pins. If interrupts are required when the DEN1 and DEN2 signals changes, the I/O pins (PA12 and PA13) has to be multiplexed to the EIC function in the GPIO module. The PCC module will still sample the DEN pins when they are multiplexed to the EIC function.

5.3.5 Backup Super Capacitor

SAM E54 Xplained Pro has a 47 mF backup super capacitor for use with the SAM E54 backup system. The super capacitor can be connected to the device as described in VBAT Backup Select.

Due to the high capacitive load represented by the super capacitor, a 220Ω limiting resistor is added to reduce inrush current. The source for charging is the targets main supply and a low-power opamp is used for disconnecting the charger input when removing power. This is added to avoid a current leak back to the main supply from the super capacitor when power is removed.

A full charge of the super capacitor from an empty state will take approximately 45 seconds and can supply the target device in backup mode with ULP running for up to ~20 hours. Other modes are not characterized, but will reduce the available time in backup mode respectively. For more information about the current consumption in other modes, refer to the electrical characteristics chapter in the SAM E54 datasheet.

Caution: Due to an issue with the VBAT pin in the A0 revision of ATSAME54P20A there is an over-consumption of current in the VBAT pin when VBAT > VDDIO. This issue renders the onboard super capacitor backup solution not usable.

5.4.4 XAM Configuration

On the SAM E54 Xplained Pro the MCU and the MCU peripherals (e.g. extensions) are powered by its own regulator as shown in the figure below. All other parts of the board, mainly embedded debugger and accompanying Xplained Pro Analog Module (XAM), are powered from a separate regulator. The current to the MCU and peripherals can be measured by connecting them to the XAM output through jumper settings.

Target MCU

On the SAM E54 Xplained Pro the XAM can be used in four configurations:

1. No current measurement or external MCU current measurement: The XAM is bypassed and thus the MCU and peripherals are supplied directly by the regulator. Set both jumpers in the "BYPASS" position. In this configuration it is also possible to connect external measurement tools on the Xplained Pro MCU power measurement header to measure MCU current directly instead of using the XAM.

2. MCU current measurement: The XAM measures only the MCU current while the peripherals are supplied directly by the regulator. For this configuration place the jumper for "I/O" (peripherals) into the "BYPASS" position and the "MCU" into the "MEASURE" position.

3. Peripherals measurement: The XAM measures only the peripherals current while the MCU is directly supplied by the regulator. For this configuration place the jumper for "MCU" into the "BYPASS" position and the "I/O" jumper into the "MEASURE" position.

4. MCU and peripherals measurement: In this configuration both the MCU and peripherals are measured by the XAM. Place both jumpers on "I/O" and "MCU" headers in the "MEASURE" position.

5.5 Kit Modifications

SAM E54 Xplained Pro has several resistors that can be used to disconnect I/O pins of the ATSAME54P20A from connectors and on-board ICs, and to disconnect power signals.

5.5.1 Enable PCC Header

The PCC header on the SAM E54 Xplained Pro board is by default not functional due to shared connections with Ethernet, QTouch, SD Card, EXT1, and EXT2.

To modify the kit to fully enable the PCC header, do the following:

• Remove the resistors: R621, R622, R623, R624, R625, R626, R628, R629, R630 to separate the Ethernet PHY from the lines

• Mount 0Ω resistors: R205, R206, R207, R208

DS70005321A-page 36

• Optionally remove: R308 (There is no contention here, but can represent a large load on the signal.)

• Remove any SD/SDIO cards from the SD Card connector

caution: PCC will not work at the same time as Ethernet, SD Card, QTouch, and I2C on EXT1.

Info: Revert the steps to restore the original functionality. Use 0Ω resistors or solder blobs to

short strap.

5.5.2 Operation at Other Voltages

The SAM E54 Xplained Pro board is operated at 3.3V by default, but it also has the possibility of running at lower voltages from an external supply. The EDBG is designed to run from a 3.3V supply and won't work on other voltages, therefore all connections from the EDBG and the on board 3.3V regulator to the ATSAME54P20A have to be removed.

To completely disconnect the EDBG and the on-board power supply from the ATSAME54P20A do the following:

SAM E54 Xplained Pro

• Remove the two jumpers from the on-board 3-pin current measurement headers (J100 and J102), and connect the two center pins (pin 2) together with a wire or an ammeter, as shown in Figure 5-7

• Remove R802, R803, R808, R809, R810, R811, R812, R813, R814, R815, R816, R817, R818, R824, R825, R826, R827

• Optionally cut J101 to remove power to the on-board current measurement headers (J100 and J102) from the on-board regulator

Figure 5-6 shows all components that have to be removed from the bottom side of the PCB for operation

at other voltages. To locate the other components, see the assembly drawing in the section above. When the components are removed, the kit can be supplied with a desired voltage through the pins marked

3.3V (pin four) and GND (pin two) on the Xplained Pro power header. To program and debug the ATSAME54P20A the 2x5 50mil Cortex debug connector has to be used with an external debugger.

Info: Operating the ATSAME54P20A on other voltages than 3.3V requires physical modifications on the kit using a soldering iron and an external debugger for programming the ATSAME54P20A. The on-board current measurement only works at 3.3V. The on-board LED is selected for 3.3V operation, the light level at 1.8V operation is very low. To increase the emitted light level the value of the series resistor can be lowered. The EDBG functionality can be restored by re-soldering the removed components and soldering a 0Ω resistor over J101.

Caution: The voltage supplied through the power header is applied directly to the ATSAME54P20A and the extension headers. Applying a voltage greater than 3.3V may damage the board permanently.

5.6 Low-Power Mode

Acquiring the lowest power consumption of the device requires some specific settings of the GPIOs in relation to the connected peripherals. The table below describes the settings needed for the lowest possible power consumption. If not otherwise noted, all pins should disable all digital logic (DIR = 0, INEN = 0 and PULLEN = 0).

Info: The power consumption on the miccrocontrollers VDD will be higher than specified in the electrical characteristics of the device due to connected peripherals.

Table 5-30. Low Power Settings

SAM E54 pin Signal State Description

PC21 ETH RESET Output low The on-board Ethernet PHY KSZ8091 continuously

generates a 50 MHz clock signal to PA14 on the SAM E54. When the KSZ8091 is in reset the clock signal is not generated and the power consumption of the SAM E54 is reduced.

DS70005321A-page 38

6. Kit Specific Data

One of the Flash user pages in the EDBG is programmed with data specific to the SAM E54 Xplained Pro. The data can be read through the I2C interface connected to the EDBG from the target application. For detailed information, refer to the EDBG User Guide. All data is stored as little endian. The table below shows the memory map for the Flash user page.

7. Appendix

7.1 Getting Started with IAR

IAR Embedded Workbench® for ARM® is a proprietary, high-efficiency compiler not based on GCC. The programming and debugging of Xplained Pro kits are supported in IAR™ Embedded Workbench for ARM using the common CMSIS-DAP interface. Some initial settings have to be set up in the project to get programming and debugging to work.

The following steps explain how to set up a project for programming and debugging:

1. Open the project that needs to be configured. Open the OPTIONS dialog for the project.

2. In the General Options category, select the Target tab. Select the "Device" for the project or the

"Core" of the device.

3. In the Debugger category, select the Setup tab. Select CMSIS DAP as the driver.

4. In the Debugger category, select the Download tab. Select the Use flash loader(s) option.

5. In the Debugger > CMSIS DAP category, select the Setup tab. Select System (default) as the

reset method.

6. In the category Debugger > CMSIS DAP, select the JTAG/SWD tab. Select SWD as the interface

and optionally select the SWD speed.

7.2 Connecting External Debuggers to an Xplained Pro Board

The Xplained Pro kits that features a 10-pin 50mil debug connector can use external debug tools like SAM-ICE™ or Atmel-ICE instead of the built-in EDBG. Evaluation kits with devices using the SWD interface on-board has a connector that is pinout compatible with the Cortex Debug Connector.

The SAM-ICE is connected to the debug connector on an Xplained Pro using either an Atmel-ICE adapter, SAM-ICE adapter, or a 10-pin 50-mil header to squid cable. When using a squid cable, see the table and figures below for how to connect the SAM-ICE to the Xplained Pro board.

Important:

If contention with the on-board EDBG occurs, power the Xplained Pro board from another input like the external power header or from the target USB. Physically removing the connection between the EDBG and the debug header by removing 0Ω resistors, where available, or cutting the tracks to the EDBG can also be done.

8. Hardware Revision History and Known Issues

This user guide is written to reflect the latest available revision of the kit. This chapter contains information about known issues, a revision history of older revisions, and how older revisions differ from the latest revision.

8.1 Identifying Product ID and Revision

The revision and product identifier of the Xplained Pro boards can be found in two ways: either through Atmel Studio or by looking at the sticker on the bottom side of the PCB.

When an Xplained Pro MCU board is connected to a computer with Atmel Studio running, an information window with the serial number is shown. The first six digits of the serial number contain the product identifier and revision. Information about connected Xplained Pro extension boards is also shown in the window.

The same information can be found on the sticker on the bottom side of the PCB. Most kits have stickers that have the identifier and revision printed in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision. Boards with limited space have a sticker with only a data matrix code, which contains a serial number string.

The serial number string has the following format:

"nnnnrrssssssssss"

n = product identifier

r = revision

s = serial number

The product identifier for the SAM E54 Xplained Pro is A09-2748.

8.2 Revision 5

Device revision A0 of ATSAME54P20A is mounted on revision 5 of SAM E54 Xplained Pro.

8.2.1 VBAT Pin

There is an issue with the VBAT pin in ATSAME54P20A revision A0. When VBAT > VDDIO there is a current over-consumption rendering the on-board super-capacitor backup solution unusable.

8.3 Revision 4

Revision 4 is the initially released revision.

The Early Adopter version of ATSAME54P20A is mounted on revision 4 of SAM E54 Xplained Pro.

8.3.1 VBAT Pin

There is an issue with the VBAT pin in ATSAME54P20A revision A0. When VBAT > VDDIO there is a current over-consumption rendering the on-board super-capacitor backup solution unusable.

DS70005321A-page 45

8.3.2 32.768 KHz Crystal

The 32.768 KHz crystal mounted on revision 4 of SAM E54 Xplained Pro is a Kyocera Crystal Device Corporation ST3215SB32768E0HPWBB 9 pF crystal. The external matching capacitors C300 and C301 are 15 pF. The crystal is matched to be driven by the SAM E54 in standard mode.

Info: Using a crystal with lower capacitive load will reduce the required drive level to keep the crystal oscillation. Revision 5 of SAM E54 Xplained Pro replaced the 32.768kHz crystal with the 5 pF version ST3215SB32768A0HPWBB to reduce the drive level from 62nW to 15nW.
