Ultra-low-power MCUs designed for IoT solutions with longer battery life and lower operating costs

Mouser now stocks the ADuCM3027 and ADuCM3029 ultra-low-power microcontrollers from Analog Devices. Serving as the brain of connected solutions, the series outperform other general-purpose processors with a high ULPBench certified score of 245.5 points, and are designed to enable longer battery life and lower operating costs in IoT applications without sacrificing security and reliability. The company’s microcontrollers are powered by a 32-bit Arm Cortex-M3 processor with 128kb (ADuCM3027) or 256kb (ADuCM3029) of on-chip flash and 64kb of SRAM with parity. Engineers can easily configure the Cortex processor to achieve the right balance of performance and power while still maintaining critical security and reliability functions. Consuming less than 30µA/MHz of current in active mode and less than 750nA in standby mode, the ultra-low-power microcontrollers enable longer operation between battery replacements or recharging, providing a better end-user experience and lower maintenance cost. This efficiency can also reduce costs for device makers by decreasing the number and size of batteries required, and enables new applications where battery replacement is impractical. The devices feature a combination of hardware and software protection mechanisms that enable faster encryption and provide read-protection to prevent the device contents from being read by unauthorized users. Additionally, in-circuit write protection prevents the device from being reprogrammed with unauthorized code. Voltage monitoring in standby mode and error correction for the flash memory increase reliability by avoiding corruptions that could result in misoperation or system crashes.
