At Analog Devices, we make technologies that sense, measure, interpret, and connect—bridging the physicaland digital worlds to form the foundation of the Internet of Things. Our technologies are designed to maximize
system-level intelligence and reliability, enabling applications where the quality and integrity of data and insights
are mission critical. The brain of the connected solution—processors—combines hardware and advanced algorithms to interpret data to deliverintelligence, functionality, and localized decision making for IoT solutions. The ultra low power microcontrollers, ADuCM3027 and ADuCM3029, aretwo of our interpreting solutions. They offer class leading, ultra low power active and hibernate modes for IoT applications where power consumption,
security, and robustness are key requirements.
