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.

Features

Fully integrated, single-chip RF transmitter (SIGFOX compliant)
System-on-chip solution including SIGFOX related protocol handling for modem operation
AVR microcontroller core with embedded firmware, SIGFOX protocol stack and ID/PAC
Supports uplink operation, i.e. transmit data telegram to SIGFOX base stations
Operating frequency range: 868.0MHz to 868.6MHz
Low current consumption: 32.7mA during telegram transmit with +14.5 dBm TX output power
Typical OFF mode current: 5nA (maximum 600nA at VS=+3.6V and T=+85℃)
Data rate: 100bit/s with DBPSK modulation
SPI interface for TX data access and transmitter configuration
Event signal indicates the status of the IC to an external microcontroller
Power-up (typical 10ms OFF mode -> IDLE mode)
Supply voltage ranges 1.9V to 3.6V and 2.4V to 5.5V (SIGFOX compliant supply range 3±5% and 3.3V to 5.5V)
Temperature range -40℃ to +85℃
ESD protection at all pins (±4kV HBM, ±200V MM, ±750V FCDM)
Small 5x5mm QFN32 package/pitch 0.5mm
