●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
