Low power wireless from ON Semi, SIGFOX and ARM for IoT developments

May 12, 2016 // By Graham Prophet
ON Semiconductor has announced two developments that it says will enable rapid deployment of Internet of Things (IoT) products. Working with SIGFOX, provider of dedicated Iot connectivity, ON has said that its AX-SFEU system-on-chip (SoC) is now fully SIGFOX Ready certified for two-way communication in Europe, with certification underway for the US.

Through the AX-SF SoC, plus its accompanying library and development system, IoT developers will be able to use SIGFOX’s long range, two-way global IoT network - resulting in a low cost, low-power device-to-cloud connectivity solution that is aimed at environmental sensors, smart meters, patient monitors, security devices, streetlights and a broad spectrum of other industrial and consumer-oriented applications.


The AX-SF SoC draws under 10 mA when receiving data and has a sensitivity of -129 dBm at 600 bits/second (bps) with GFSK modulation. The reference design, which does not require an expensive front-end module, features a 23 dBm transmitter and has a 220 mA current consumption, enabling designers to markedly extend communication range while maximizing battery life.


ON Semiconductor also announced that it is now an official ARM mbed partner. The NCS36510 2.4 GHz IEEE 802.15.4 compliant transceiver platform will include the mbed OS and Thread stack. Access to the ARM mbed ecosystem in combination with Thread will, ON comments, aid IoT developers by helping them to produce more agile, robust, cost-effective solutions with end-to-end security and lower power budgets that better address their application demands.


Stuart Lodge, Executive Vice President of Global Sales and Partners at SIGFOX, adds, “Our fast-growing operated network, currently in 18 countries including the US and registering over 7 million devices, requires a reliable supply of high performance, low-cost and extremely energy-efficient integrated circuits, and our collaboration with ON Semiconductor helps assure those solutions will be available to our customers.”


ON further adds, “Meanwhile for the LAN environment, our industry leading 802.15.4 platform based on the NCS36510 now provides users access to the ARM mbed ecosystem coupled with the benefits of Thread for security and interoperability. SIGFOX, in combination with Thread, also has great potential for use cases where multiple connectivity solutions can be mixed to create new user experiences.
