1 min read

Atmosic, a specialist in energy harvesting wireless platforms for the Internet of Things (IoT), has unveiled the ATM33 Series Bluetooth 5.3 family of high-performance system-on-chips (SoCs).

Atmosic said that it was supplementing its eco-friendly SoC portfolio with the addition of the ATM33 series of products to support battery-free operations. The ATM33 SoCs come with a 0.7mA receiver and a transmitter that can operate efficiently with output power from 0dBm to 10dBm. The company claims that's these solutions provide 3-to-5x longer battery life compared to many competitor devices.

“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.”

The ATM33 integrates a power optimised Arm Cortex M33F that can operate up to 64MHz and supports Arm TrustZone for security. The new series provides 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 5x5 40-pin QFN, a 7x7 56-pin QFN, and a wafer level chip scale packaging (WLCSP) for ultra - compact applications. Sampling available in Q1 2022.

Atmosic has also announced $72 million in new funding led by Sutter Hill Ventures.

The company has grown significantly during the past year with a 10x increase in shipments, and a 500% expansion of the company’s customer base.

“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 fullfill our mission of a battery-free IoT.”
