1. If VDD_IO ramps cannot be guaranteed, an external reset circuit is recommended, see the AX8052 Application Note: Power On Reset
2. The output power of the AX−Sigfox can be programmed in 1 dB steps from 0 dBm – 14 dBm. Current consumption values are given for a
matching network that is optimized for 14 dBm output. 0 dBm transmission with typically 10 mA can be achieved with other networks that
are optimized for 0 dBm operation.
3. Internal 20 MHz iscillator, voltage conditioning and supervisory circuit running.
