Energy harvesting wireless platform developer Atmosic has launched what it says is the lowest power Bluetooth 5.3 SoC advanced product family with energy harvesting technology.

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. [2]

Figure 1 shows to reduce the need for costly battery replacement in connected products and its associated environmental toll, Atmosic is supplementing its eco-friendly SoC portfolio with the addition of the ATM33 series of products that supports unparalleled battery life and battery-free operations. 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. [4]

The ATM33 series continues Atmosic's track record of innovation. 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. [3]

Other features include:

• RAM configuration: 16 KB to 128KB in 16 KB step sizes• 6 MHz / Optional 32.768 kHz Crystal Oscillator
• 6 MHz / Optional 32.768 kHz Crystal Oscillator
• On-chip RF Energy Harvesting
• Bluetooth Low-Energy 5.3 compliant
• Supports photovoltaic, thermal, motion and other energy harvesting technologies

Furthermore, 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. Applications include:

• Industrial and enterprise: Industrial IoT Sensors and remote monitors
• Healthcare
• Consumer: Home automation and human interface devices (HIDs)

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 will be available in Q1 2022. [1]
