General Description

Introduction

The Atmel

ATA8520 is a highly integrated, low-power RF transmitter with an integrated AVR

microcontroller for

applications using the wide area SIGFOX

™

network

The Atmel ATA8520 is partitioned into three sections: an RF front end, a digital baseband and the low-power 8-bit AVR

microcontroller. The product is designed for the ISM frequency band in the range of 868.0MHz to 868.6MHz. The external

part count is kept to a minimum due to the very high level of integration in this device. By combining outstanding RF

performance with highly sophisticated baseband signal processing, robust wireless communication can be easily achieved.

The transmit path uses a closed loop fractional-N modulator.

The SPI interface enables external control and device configuration.

Figure 1-1

shows an overview of the main functional blocks of the Atmel ATA8520. External control of the Atmel ATA8520 is

performed through the SPI pins SCK, MOSI, MISO, and NSS. The functionality of the device is defined by the internal

firmware and processed by the AVR. SPI commands are used to control the device and to start the data telegram

transmission. The end of the telegram transmission is signaled to an external microcontroller on pin 28 (PB6/EVENT).

It is important to note that all PWRON and NPWRON pins (PC1..5, PB4, PB7) are active in OFF mode. This means that

even if the Atmel ATA8520 is in OFF mode and the DVCC voltage is switched off, the power management circuitry within the

Atmel ATA8520 biases these pins with VS.

The AVR microcontroller ports can be used as button inputs, LED drivers, EVENT pin, general purpose digital inputs, or

wake-up inputs, etc. Functionality of these ports is already implemented in the firmware.
