Product Description

Product Details
The ADuCM3027/ADuCM3029 microcontroller units (MCUs) are ultra low power microcontroller systems with integrated power management for processing, control, and connectivity. The MCU system is based on the ARM Cortex-M3 processor, a collection of digital peripherals, embedded SRAM and flash memory, and an analog subsystem which provides clocking, reset, and power management capability in addition to an analog-to-digital converter (ADC) subsystem.
The following are the key features of the ADuCM3027/ADuCM3029 MCUs:
Industry leading ultralow power consumption.
SensorStrobe™ for precise time synchronized sampling of external sensors.
Works in hibernate mode, resulting in drastic current reduction in system solutions. Current consumption reduces by 10 times when using, for example, the ADXL363 accelerometer.
Software intervention is not required after setup.
No pulse drift due to software execution.
Leading edge security.
Fast encryption provides read protection to customer algorithms.
Write protection prevents device reprogramming by unauthorized code.
Robust operation.
Full voltage monitoring in deep sleep modes.
ECC support on flash.
Parity error detection on SRAM memory.
Failure detection of 32 kHz LFXTAL via interrupt.
Applications
Internet of Things (IoT)
Smart machine, smart metering, smart building, smart city, smart agriculture
Wearables
Fitness and clinical
