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
