STMicroelectronics unveils latest radio chip for the Internet-of-Things (IoT), S2-LP transceiver, that delivers high energy efficiency for smart connected objects to operate for up to 10 years without replacing batteries.
The radio chip is is ideal for networked devices, such as alarm systems, surveillance equipment and smart energy-metering solutions, as well as long-range radio links used to connect devices like remote sensors directly to the Cloud without a local gateway. Other applications include building automation, industrial monitoring and control, and systems for managing lighting, traffic, or parking in smart cities.
The device operates in unlicensed sub-1GHz frequency bands, which are available globally. Ultra-narrowband operation allows highly efficient use of radio spectrum and reliable data exchange up to long distances using low-power signals.
In addition, the transceiver enables connectivity to the Sigfox global network, which is being rolled out worldwide to provide a reliable cost- and energy-efficient communication solution for billions of sensors and smart things.
“Building on our strengths in MEMS Sensors, Analog and Microcontrollers, in 2009 we saw the coming need to support emerging IoT applications with a low-power ISM radio for medium-long-range wireless connections and we developed and introduced our own SPIRIT1 low-power sub-1GHz radio that is currently in many applications available in the market,”said Benedetto Vigna, Executive Vice President, General Manager, Analog and MEMS Group, STMicroelectronics.
“Now, in partnership with Sigfox, we are opening a new era in ISM radios for the IoT to extend battery life from months to more than 10 years while preserving the robustness and reliability of the connection and reducing maintenance costs for remote and difficult-to-reach sensors," Vigna.
The S2-LP long-range, low-data-rate transceiver is in production now in a 4mm x 4mm QFN24 package, priced $1.15 for orders of 1000 pieces.
