AXSEM and SIGFOX Announce ‘Ultra-low-power’ System-on-Chip Solution for Long-range Internet of Things Connectivity

AXSEM’s AX8052F143 ‘Lowest-power-radio’ SoC Receives SIGFOX ReadyTM Certification for Two-way IoT Network

DUBENDORF, Switzerland & ZURICH, Switzerland & LABEGE, France — (BUSINESS WIRE) — December 2, 2014 — AXSEM, a global leader in lowest-power radio microcontrollers, and SIGFOX, the pioneer in cost-effective, energy-efficient Internet of Things connectivity, today announced that AXSEM’s system-on-chip (SoC) with an AX8052 microcontroller has been certified SIGFOX Ready™ for two-way connectivity.

AXSEM’s IC, library and development system enable IoT developers to easily use SIGFOX’s long-range, two-way wireless Internet-dedicated network with AXSEM’s superior lowest-power radio technology. This combination of low costs, lowest-power consumption and international coverage makes it the ideal solution for environmental sensors, smart meters, patient monitors, security devices, streetlights and many more applications.

The SIGFOX network eliminates the cost and energy-use barriers to wide implementation of IoT and M2M solutions by providing small-message communication and greatly extending the battery and service life of connected devices.

“AXSEM was very early to recognize and respond to the demand for transceivers that provide extremely low-power, wireless connectivity for the Internet of Things,” said Stuart Lodge, executive vice president of global sales at SIGFOX. “Our fast-growing network requires a reliable supply of high-performance, low-cost and extremely energy-efficient integrated circuits, and our collaboration with AXSEM helps assure those solutions will be available to our customers.”

"AXSEM is focused on enabling IoT developers with easy-to-use development tools to bring their SIGFOX devices quickly to the market," said Dr. Thomas Wolff, CEO of AXSEM. "Our AX8052F143 lowest-power radio microcontroller solution gives those developers robust and reliable two-way connectivity to the SIGFOX global network.”

The AXSEM AX8052F143 receives with 9.5 mA current and -129 dBm sensitivity at 600 bps GFSK. The chip features a 6 dBm transmitter with only 10 mA current consumption or 16 dBm with 45 mA, enabling designers to maximize battery life while extending communication range. A frequency range from 27 to 1050 MHz completes the excellence of the device and has made the AX8052F143 an industry-leading performer for the past three years.
