Analog Devices announced an ultra-low-power microcontroller unit (MCU) that addresses the rapidly growing need for embedding advanced algorithms while consuming the lowest system power at Internet of Things (IoT) edge nodes. The ADuCM4050 includes an ARM Cortex-M4 core with floating-point unit, expanded SRAM, and embedded Flash memory in order to allow localised decision making and ensure that only the most important data is sent to the cloud.
The new MCU uses SensorStrobe technology allowing it to remain in a low-power state while sensors are still collecting data. Key feature enhancements have been added for operation in harsh environments. Security is also enhanced by encryption which provides stronger IP protection for the designer and better protection against malware and misuse. Among these are AES 128/256, SHA 256, block ciphers for code protection, key wrap and HMAC.
The ADuCM4050 MCU targets applications where long battery life is critical, but where security, performance integrity, and the ability to pre-process and filter sensor data to eliminate artifacts and noise are also requirements. Applications include clinical vital-signs monitoring, smart energy management, and asset health/factory equipment reporting.
