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. For a feature comparison across the ADuCM3027/ADuCM3029 product offerings, see Table 1. Table 1. Product Flash Memory Options Device Embedded Flash Memory Size ADuCM3029 256 kB ADuCM3027 128 kB System features that are common across the ADuCM3027/ADuCM3029/ADuCM3029-1/ADuCM3029-2 MCUs include the following: Up to 26 MHz ARM Cortex-M3 processor Up to 256 kB of embedded flash memory with error correction code (ECC) Optional 4 kB cache for lower active power 64 kB system SRAM with parity Power management unit (PMU) Multilayer advanced microcontroller bus architecture (AMBA) bus matrix Central direct memory access (DMA) controller Beeper interface Serial port (SPORT), serial peripheral interface (SPI), inter-integrated circuit (I2C), and universal asynchronous receiver/transmitter (UART) peripheral interfaces Cryptographic hardware support with advanced encryption standard (AES) and secure hash algorithm (SHA)-256 Real-time clock (RTC) General-purpose and watchdog timers Programmable general-purpose input/output (GPIO) pins Hardware cyclic redundancy check (CRC) calculator with programmable generator polynomial Power-on reset (POR) and power supply monitor (PSM) 12-bit successive approximation register (SAR) ADC True random number generator (TRNG)To support low dynamic and hibernate power management, the ADuCM3027/ADuCM3029 MCUs provide a collection of power modes and features, such as dynamic and software controlled clock gating and power gating.The ADuCM3029-1 and ADuCM3029-2 MCU models share the same features and functionality as that of the ADuCM3029 MCU. All specifications pertaining to the ADuCM3027 and ADuCM3029 are also applicable to the ADuCM3029-1 and ADuCM3029-2.For full details on the ADuCM3027/ADuCM3029 MCUs, refer to the ADuCM302x Ultra Low Power ARM Cortex-M3 MCU with Integrated Power Management Hardware Reference Manual.Product Highlights Industry leading ultralow power consumption. Robust operation, including full voltage monitoring in deep sleep modes, ECC support on flash, and parity error detection on SRAM memory. Leading edge security. Fast encryption provides read protection to customer algorithms. Write protection prevents device reprogramming by unauthorized code. Failure detection of 32 kHz LFXTAL via interrupt. 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.
