devices. The sensor solutions offer best-in-class performance for headphones, fitness bands, smart watches and phones. They are integrating three LED outputs, a photodetector, a low-noise analog front-end, a digital interface and a state machine into a single die. For best application results the bare die is either packaged with an infrared or a green LED or can drive up to three external LEDs. The sensors offer a fully integrated solution for optical heart rate measurement featuring an I²C interface for a programmable sample rate of up to 256 per second. This allows a significantly better signal-to-noise ratio (SNR) than discrete alternatives. Additionally, monitoring algorithms can filter out motion artifacts and deliver precise heart rate and pulse oximetry measurements during exercise. High optical sensor resolution enables accurate measurement across the widest possible variety of skin types, while high optical sensitivity reduces photo diode area and drives down LED power consumption with a typical 300 μA LED current on fair skin. A standby current of just 0.3 μA further reduces power consumption. Availability Infineon and GoerTek sensor solutions are available either as bare die or as packaged products with application algorithm fromInfineon’s long-term partnerGoerTek. Packages measure just 3.94 mm x 2.36 mm x 1.35 mm. Packaged samples are available now, with volume production targeted in August 2016. In addition to the

milliamperes (mA) of current when receiving data and has a sensitivity of -129 decibel-milliwatt (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 only 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 gigahertz (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 again prove highly beneficial for IoT developers, 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. “ON Semiconductor was very early to recognize and respond to demands for transceivers that provide extremely low-power, wireless connectivity for the IoT,” states Stuart Lodge, Executive Vice President of Global Sales and Partners at SIGFOX. “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 extremelyenergy-efficientintegrated circuits, and our collaboration with ON Semiconductor helps assure

bare die chips from Infineon, GoerTek is offering starter kits and demonstration boards for designers looking to rapidly evaluate and test the technology for use in their smart applications. ON Semiconductor Expands Low Power Wireless Solutions Portfolio with SIGFOX and ARM for Rapid IoT Deployment ON Semiconductor (Nasdaq: ON), driving energy efficient innovations, has announced two major strategic developments to enable rapid deployment of Internet of Things (IoT) solutions. Working in conjunction with SIGFOX, the world’s leading provider of dedicated connectivity for the Internet of Things (IoT), ON Semiconductorhasconfirmed that its AX-SFEU system-on-chip (SoC) is now fully SIGFOX Ready™ certified for optimal 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 easily use SIGFOX’s long range, two- way global IoT network – resulting in a low cost, low-power device-to- cloud connectivity solution that is highly optimized for 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
