Ultra Low Power MCU Enables 10 Times System-Level Power Savings and Floating-Point Operation in IoT Applications
14 März 2017 - 1:00PM
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®-M4 core 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.
