The ATA8520 is a Transmitter IC for operation in the 868MHz SIGFOX network. It can be used to provide equipment for the Internet of Things (IoT) and other machine-to-machine communication using an air interface to the SIGFOX proprietary network. Industrial and consumer applications include environmental sensors, smart meters, patient monitors, home automation and building security systems. The ATA8520 incorporates an RF front end, a digital baseband and a microcontroller in a single chip. Firmware stored in internal memory supports the chips' operations, including handling of the SIGFOX protocol. A serial peripheral interface provides for external control and configuration. The single chip solution provides extreme low power consumption of 32.7mA current at +14.5dBm output power and 5nA in Off mode current. The Supply-voltage range is 1.9-3.6V.
