The ATM33 Series Bluetooth 5.3 family of system-on-chips (SoCs) developed by Atmosic integrates a Bluetooth 5.2 compliant radio with ARM Cortex M33F application processor with RF energy harvesting source. It has 128 KB Random Access Memory (RAM), 64 KB Read-Only Memory (ROM), 512 KB nonvolatile memory (NVM), with ARM TrustZone enabled security features, and state-of-the-art power management to enable maximum lifetime in battery-operated devices.

The chip has a 0.7 mA radio receiver and a 2.1 mA radio transmitter power consumption with support for low duty cycle operation allows systems to run for significantly longer periods without battery replacement.

It also supports other external energy harvesting sources, including photovoltaic, TEG (Thermoelectric generator), and motion with various wake-up mechanisms to provide options for further power consumption reduction.

“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, a member of the Atmosic board of directors and managing director at Sutter Hill Ventures which led the funding round

Atmosic’s business has grown significantly during the past year with a 10x increase in shipments, and a 500% expansion of the company’s customer base, including the recent partnership announcement with Universal Electronics for smart home devices.

“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.

“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.”
