Launch of S2-LP Internet of Things Wireless Chip Transceiver
Simplified Access for Reliable, Efficient, and Cost-Effective IoT Connectivity

STMicroelectronics (hereinafter ST) has launched the S2-LP transceiver, an Internet of Things wireless chip with exceptional energy efficiency that enables smart connected products to operate for up to 10 years without battery replacement.

ST's new S2-LP transceiver is an ideal solution for long-range wireless links used in networked devices such as alarm systems, surveillance devices, and smart energy metering solutions, as well as remote sensors that connect directly to the cloud without using a local gateway. It is also suitable for applications such as building automation, industrial monitoring and control, and systems for lighting, traffic, and parking management within smart cities.

This device operates in the license-free sub-1GHz frequency band and is available worldwide. Such ultra-narrowband operation enables efficient use of the wireless spectrum and reliable data exchange over long distances using low-power signals.

Additionally, it is capable of connecting to the global network of Sigfox, which is spreading worldwide to provide reliable, cost-effective, and energy-efficient communication solutions for billions of sensors and smart devices.

Benedetto Vigna, Senior Vice President and Business Unit Head of ST's Analog and MEMS Group, stated, "In 2009, when ST was building capabilities in MEMS sensors, analog, and microcontrollers, we foresaw the need for low-power ISM wireless support for medium to long-range wireless connectivity for emerging IoT applications and developed SPIRIT1, a low-power sub-1GHz wireless chip. This product is currently used in various applications in the market," and added, "Now, through collaboration with Sigfox, we are opening a new era of ISM wireless for IoT."

Tony Francesca, Vice President of Global Ecosystem Partnerships at Sigfox, stated, "We have provided a new dimension of method for connecting the physical world to the cloud by leveraging our global network optimized for minimizing device power consumption and costs," and further noted, "ST has supported Sigfox through integration in the S2-LP wireless device. This will help system developers leverage our rapid global infrastructure and ecosystem to realize IoT concepts into practical implementations."

The S2-LP, a long-range, low data rate transceiver, is currently in mass production in a 4mm x 4mm QFN24 package at a unit price of $1.15 per piece when ordering 1,000 units.
