A provider of energy harvesting wireless platforms for IoT, Atmosic raises $72 million in new round of funding led by Sutter Hill Ventures.
“We continue to see tremendous market growth for wireless battery-powered devices especially in Consumer, Home, and Industrial applications. It is exciting to see Atmosic leverage its breakthrough low power and energy harvesting technologies to expand its portfolio and gain customer traction in these markets. Having backed Atmosic from day one, we are excited to double down with a super pro-rata investment to create the IoT wireless franchise,” said Stefan Dyckerhoff, managing director at Sutter Hill Ventures and member of the Atmosic board of directors.
The California-based fabless semiconductor company also unveiled its new ATM33 Series Bluetooth 5.3 family of SoCs. The new product leverages energy harvesting technology to offer energy efficiency and eliminate the cost and waste of constantly replacing batteries in connected products. The ATM33 SoCs provide best-in-class radio power performance with a 0.7mA receiver and a ground-breaking transmitter that can operate efficiently with output power from 0dBm to 10dBm. These solutions provide 3-to-5x longer battery life compared to the competition.
“The need for extended battery life and solutions that incorporate energy harvesting to significantly enhance the end-user experience and to lower ownership cost for enterprises is growing. Atmosic has been extremely successful in delivering innovative solutions in these applications. We are excited to support Atmosic in expanding its vision with this additional investment,” said Rajeev Madhavan, founder, and general partner at Clear Ventures and member of the Atmosic board of directors.
The ATM33 integrates a power-optimized Arm Cortex M33F that can operate up to 64MHz and supports Arm TrustZone for robust security. The new series has improved energy harvesting efficiency, a wider harvesting input range, a lower cold start voltage, Lithium-Ion battery support, and low-power voice processing. In addition, the Atmosic Sensor Hub supports CPU-less operations, allowing the SoCs to perform functions such as access memory and transmit beacons even while in deep sleep. The ATM33 series is available in three packages: a 5×5 40-pin QFN, a 7×7 56-pin QFN, and a wafer level chip scale packaging (WLCSP) for ultra-compact applications. Sampling available in Q1 2022.
“Building upon our proven ultra-low-power radio technology and market success, we are enhancing the SoCs with the processing power of the Arm Cortex-M33F, embedded non-volatile memory, as well as the latest Bluetooth standard,” said David Su, CEO of Atmosic. “With the launch of our new product family, Atmosic is supporting the strong growing demand for more environmentally friendly solutions to reduce the billions of batteries that are disposed of every year.”
Over the past year, Atmosic witnessed constant business growth with 10X increase in shipment and a 500% expansion of its customer base. The company recently announced its partnership with Universal Electronics Inc. Atmosic continues to enhance its ultra-low power and energy harvesting technology roadmap, expand globally and deliver breakthrough IoT innovations.
“Atmosic’s strong growth is proof of the demand for more environmentally friendly and cost-efficient solutions to reduce the billions of batteries that are disposed of every year,” said David Su, CEO of Atmosic. “With this new funding and the introduction of the ATM33 series, Atmosic is setting a new benchmark for the IoT industry with best-in-class power-efficiency and performance to fulfill our mission of a battery-free IoT.”
