ATA8520D-GHQW Product Details

The ATA8520D-GHQW 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 ATA8520D-GHQW 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.
