Designed to support “unparalleled” battery life and battery-free operations, the ATM33 Series Bluetooth 5.3 family of SoCs are offered as providing best-in-class radio power performance with a 0.7mA receiver and a transmitter that can operate efficiently with output power from 0dBm to 10dBm. These solutions, says the company, provide 3-to-5x longer battery life compared to the competition.

“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,” says 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-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 is expected to be available in Q1 2022.
