NORWOOD, Mass. -- (Business Wire)
Analog
Devices, Inc. today 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 MCU includes an ARM® Cortex®-M4core with floating-point unit, expanded SRAM, and embedded flash
memory in order to allow localized decision making and ensuring that
only the most important data is sent to the cloud. The new MCU uses
SensorStrobeTM technology allowing it to remain in a low
power state while Analog Devices’ sensors and RF technology are still
collecting data. This enables the ADuCM4050 MCU to deliver over 10 times
system-level power savings that result in extended battery life or
longer time between battery charges. Key feature enhancements have been
added for operation in harsh environments.

Security is also enhanced with the ADuCM4050, due to its 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 new
ultra low power MCU complements Analog Devices’ already existing
class-leading ADuCM302x series of parts and offers pin compatibility.
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.
The ADuCM4050 supports multiple digital- and analog-sensor inputs via
its SensorStrobe technology so they can be combined to analyze their
data for smarter, more sophisticated functionality. Therefore, there is
no need to wake up the microcontroller frequently to report routine or
partial data, thus saving significant power over the long term.
The extremely low power requirements of the ADuCM4050 are seen in its
40μA/MHz active-mode consumption, which drops to 680nA in hibernate
mode. The large amount of SRAM and flash memory – 128kB and 512kB,
respectively – and the ability to retain almost all of the SRAM, enables
it to get data ready quicker when it wakes up from hibernate (sleep)
mode, another major power-saving feature.
The ADuCM4050 seamlessly works with the industry leading,
ultralow-power, low-g ADXL362 and the newly announced ADXL372 micropower
high-g MEMS accelerometer as part of Analog Devices’ portfolio of ultra
low power technology. SensorStrobe technology also works seamlessly with
these sensors to unlock additional system-level power savings.
