Single Chip SIGFOX™ compliant RF Transceiver 868MHz

Еще документы...

The ATA8520D is a Transceiver IC for up- and downlink 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 incorporates an RF front end for up- and downlink to a SIGFOX™ base station, a digital baseband and a microcontroller in a single chip. Firmware stored in internal memory supports the chip’s operations, including handling of the SIGFOX™ protocol. A serial peripheral interface provides for external control and configuration. The single chip solution provide extreme low power consumption of 32.7mA current at +14.5dBm transmit output power, 10.4mA in receive mode and 5nA in Off mode. The Supply-voltage range is 2.9V-3.1V (3V operation mode) or 3.3V-5.5V (5V operation mode).
