Description
This user guide describes an evaluation kit and the extension boards for a SIGFOX
application. This application uses an Atmel ATmega328P AVR microcontroller to
read out an AT30TS75A temperature sensor using the built-in TWI connection and controls
the RF telegram transmission using the SIGFOX ATA8520D V1.3 transceiver device. This
application requires a SIGFOX base station infrastructure to capture the RF telegram and
supply payload data at the SIGFOX back end of the SIGFOX Cloud. For more information
on operating the SIGFOX network and SIGFOX Cloud, see http://www.sigfox.com
information.
The evaluation and development kit tool packs are available for download from the Atmel
website: http://www.atmel.com/devices/ATA8520.aspx. These tool packs include
● The ATAN0054 quick start guide for the kit and the Atmel ATAN0104 user guide

1. Getting Started with the ATA8520-EK1-E Kit
Figure 1-1 shows the components which are included in the evaluation kit. The kit includes
● A single PCB ATAB0101A with
● An Atmel
● An Atmel ATmega328P AVR
● An AT30TS75A temperature sensor with TWI
● An 868MHz monopole antenna for connection to the SMA connector
The kit requires an external power supply or battery for 3.0V to 3.3V at 50mA which is not included in the kit.
Figure 1-1. ATA8520-EK1-E Kit Components

microcontroller at 8MHz
The 868MHz monopole antenna is connected to the SMA connector of the PCB and the external power supply or battery has
to be connected to connector X1.
Caution: Ensure correct polarity at the connection to avoid damage to the equipment. The PCB has no reverse polarity
protection for the power supply connection.
The kit comes with preconfigured devices for starting the Flash application of the Atmel ATmega328P once the power is
applied. This application controls the RF telegram transmission and reads out the temperature sensor at one-hour intervals
or when pressing the SW1 button. The red LED1 starts blinking for about 7-8s, i.e. during telegram transmission. The device
then enters power-down mode until a wake-up from the internal timer or a button press occurs.
Every fifth transmission is executed as an uplink/downlink request, i.e. it will first transmit the RF telegram with sensor data
and requests a payload data packet from the SIGFOX cloud via a base station. The execution of these request will take
about 40-50s.
The Atmel ATA8520D device includes the SIGFOX ID and PAC registration code (see label attached to PCB) to register the
kit with the user's account for the SIGFOX back end. The user has to open a SIGFOX cloud account to access the back end.
From this account the data payload transmitted from the devices can be retrieved in various ways as described in the
SIGFOX online help.
An Atmel debugger (Atmel JTAGICE3 or Atmel ICE), which can be connected to connector XISP1, is required for application
development. Please see the marker for pin1 to connect with the correct orientation. The debugger can only be used if
Atmel Studio 6 is installed in the front end. Atmel Studio 6 can be downloaded from http://www.atmel.com with additional
user instructions and tools. The documentation for the kit components and for the software is included in the tool pack zip
folder [7] which can be downloaded from the Atmel website [5].
The kit and the boards are preprogrammed and temperature calibrated to operate at room temperature (24°C). For operation
with a wider temperature range a temperature calibration as described in “ATAN0142 - ATA8520D Crystal Calibration” has
to be applied. This is mandatory to comply with the CE certification for the kit and boards and is valid for a temperature range
of –20°C to +55°C.

4. ATA8520D SIGFOX Certified Transceiver
The Atmel ATA8520D SIGFOX™ transceiver includes the SIGFOX protocol library and a SPI communication interface for
controlling device operation. The transceiver buffer of the device is loaded with a max. of 12 bytes of payload data for
transmission in the 868MHz ISM band. The ATA8520D device can also receive payload data with 8 Bytes from the SIGFOX
cloud when transmitting an uplink/downlink request. The Atmel ATA8520D device is certified by SIGFOX to participate in
their network. A second certification step for the module or system including antenna is also required with a classification of
the module or system RF performance, i.e. radiated RF output power. As a result, the RF path including antenna must also
have SIGFOX certification.
The key parameters for the RF link are:
● RF channels: 868.0 to 868.6MHz for uplink and 869.4 to 869.65MHz for downlink
● RF output power: max. 14.5dBm
● RF sensitivity: –126dBm
● Data rate: 100bit/s with DBPSK modulation for uplink and 600bit/s with GFSK modulation for downlink
● Data payload: max. 12byte with LSB first for uplink and 8 bytes for downlink
● Duty cycle: max. 5 telegrams/hour, i.e. < 1% for uplink and max. 4 telegrams/day for downlink
The data transmission is AES encrypted.
The SIGFOX ID and PAC registration code are printed on a label attached to the PCB and can also be read out from the
device using the SPI command interface. This ID and code are required for registering the device with the user's account for
the SIGFOX back end.

5.1 ATA8520-EK1-E Power Consumption and Battery Selection
When using the PCB in standalone mode, the AVR® microcontroller can be set to a power-down mode while running the
Timer2 with the external 32.768kHz crystal. This will reduces the mean current consumption to ~10 to 20µA (see Table 5-1
for 5 messages per day). In this mode the sensor power is switched off and the Atmel
and the MCU only wakes up by pressing the button, applying an external interrupt signal or from the internal Timer2
interrupt.
Figure 5-2 shows the typical current consumption profile from the different operating modes of the Flash application during a
telegram transmission. This allows the calculation of a mean current consumption depending on the wake-up intervals.
The shown current profile is a typical profile and depends on the Flash application of the Atmel ATmega328P device and the
attached sensors.
During the telegram transmission the MCU is performing the LED flashing to indicate activity. This increases the current
consumption and can be replaced by setting the MCU in power-down mode. When the transmission is finished an event is
generated on pin PB6 of the ATA8520D which can be used to wake-up the MCU.

Table 5-1 summarizes battery service life for a typical Lithium battery which can be used with the ATAB0101A. When
selecting the battery, it is important to know the peak current consumption which has to be supplied by the battery cells. It is
assumed that the battery voltage drops from the initial value of 3V down to 2V at the end of its service life. The self-discharge
is defined by the manufacturer as typically 1% per year at an ambient temperature of 20°C.

When operating in uplink/downlink mode the transmission and reception will take about 40 to 50 seconds. In this period the
device will first send a data telegram three times as shown in Figure 5-2, followed by an idle mode with about 4.5mA current
consumption for about 20s and will then enter the receive mode for about 20s with 19mA current consumption. Finally a
confirm telegram is sent for about 2s. This uplink/downlink mode is only possible for max. 4 transmissions/day and has to be
added to the Mean Current consumptions in Table 5-1.
During the uplink/downlink operation the MCU can be placed in power-down mode and can wake-up by the event of the
ATA8520D.
5.2 Connector Description
The PCB has several connectors which are used differently depending on the PCB configuration. Table 5-2 summarizes the

The green LED LD1 is connected to the sensor power and indicates if the sensor power is switched on.
The red LED LD2 is connected to port PD5 on Atmel® ATmega328P and to the connectors X2/pin8 and X6/pin6 and can be
controlled by the MCU application.
The button SW1 is connected to port PD6 on Atmel ATmega328P and to the connectors X2/pin4 and X6/pin7 and can be
read by the MCU application.
The PCB contains a temperature sensor connected to the TWI bus of the MCU and in addition two footprints for additional
sensors, i.e. an air pressure sensor and a humidity sensor device. With the TWI connector X8 additional sensors can be
connected as long as the current on the 3.3V supply will not exceed 50mA.
The PCB contains also a AES crypto device connected to the SPI bus which can be controlled from the MCU or from the RF
device. Currently only the MCU will control this device using the AES_NSS signal for the chip select. This chip select is
connected to port pin PD7 and to the connectors X2/pin10 and X6/pin8.

The source code for all applications is available within the tool pack distribution [7].
The program flow for the Flash application is illustrated in Figure 6-1. The application first initializes all required peripherals
such as pins, timers, SPI, ADC, UART, TWI and the ATA8520D SIGFOX transceiver by reading out the ID/PAC information
required for SIGFOX
™
registration. This ID/PAC data is send via the UART interface to a PC terminal application. The
Timer2 is used as a real-time clock and uses either the
● External 32.768kHz crystal for the ATA8520-EK1-E kit or the
● Internal system clock for the ATA8520-EK2-E and ATA8520-EK3-E kits.
Timer2 is configured to wake up the MCU every hour or every 15 minutes. Pressing button SW1 also causes the MCU to
wake up. The temperature sensor is powered up and read out and after this a data telegram is transmitted. The device then
enters power-down mode again until the next wake-up by the RTC (or manually by pressing SW1).

During the step Initialisation1 the application will perform a check for the device version to be V1.3. This device version
supports the temperature drift calibration and includes fixes for the test function. Previous device version will not support this
modes
6.1 Software Development
Atmel® Studio 6 is required for software development and can be downloaded from the Atmel website [5]. The tool pack [7]
with software and documentation is also required. When unpacking the tool pack, the folder structure as described in Section
3. “Tool Pack for the Kits” on page 7 is generated.
Four different applications and folder structures are included with sample applications for the kit versions.
..\ATA8520-EK1-E\ATAB0101A ATmega328P project for ATA8520-EK1-E kit
..\ATA8520-EK2-E\XplainedMini_SW Xplained Mini project for ATA8520-EK2-E kit
..\ATA8520-EK2-E\ArduinoUNO_SW Arduino IDE sketch for ATA8520-EK2-E kit
..\ATA8520-EK3-E\SAMD21_XplainedPRO_SW SAMD21 Xplained Pro project for ATA8520-EK3 kit
The Atmel Studio 6 installation makes all USB drivers and debugger supports available when plugging in the development
kits. Not included is the ATA8520-EK1-E standalone kit which requires an AVR
ISP-microcontroller for debugging and programming.
When using the Arduino UNO sketch application, the Arduino IDE has to be installed first along with the Atmel ATA8520D
library.
