Implementing cloud transfer of only critical data by local decision
Maintain low power while collecting data using RF technology

Analog Devices has launched an ultra-low-power microcontroller (MCU) to address the demand for implementing advanced algorithms while minimizing system power consumption at Internet of Things (IoT) edge nodes.

The ADuCM4050 MCU consists of an ARM® Cortex®-M4 core with a floating-point unit, expanded SRAM, and embedded flash memory, enabling local decision-making and transmitting only critical data to the cloud.

The new MCUs utilize SensorStrobe ^™ technology, which allows ADI's sensors and RF technology to remain in a low-power state while collecting data. This reduces system-level power consumption by more than 10x, extending battery life and extending product usage between charges.

The ADuCM4050 MCU provides designers with superior IP protection through encryption and enhances security with malware and misuse prevention. It includes security features such as AES 128/256, SHA 256, block cipher for code protection, key wrap, and HMAC, and complements Analog Devices' existing ADuCM302x series, providing pin compatibility.

The ADuCM4050 MCU is focused on applications that require long battery life, but also security, performance integrity, and the ability to preprocess and filter sensor data to remove noise.
