Use ADuCM302x microcontroller
Increased battery replacement and recharge cycles for the device

Analog Devices, a global leader in high-performance semiconductors for signal processing applications, has announced the ADuCM302x series of ultra-low-power microcontrollers. The newly announced ADuCM302x series is designed to extend battery life and reduce operating costs in Internet of Things (IoT) applications without compromising performance capabilities such as security and reliability.

Using the ADuCM302x microcontroller, which consumes less than 38 uA/MHz of current in active mode and less than 750 nA of current in standby mode, allows the device to be used for a longer period before the battery needs to be replaced or recharged, making it more convenient for end users and reducing maintenance costs. Due to this excellent efficiency, the number and size of batteries required are reduced, which lowers costs for device manufacturers and can bring new attention to applications where battery replacement is difficult.

While alternative products on the market often sacrifice key performance to meet efficiency benchmarks, the ADuCM302x series supports all features for stability and safety. Acting as the brain of connected solutions, this microcontroller is Analog Devices' flagship product that provides system-level solutions for the Internet of Things and enables intelligent decision-making closer to sensors. The ADuCM302x series complements the ADI board portfolio with compatible sensing and wireless communication technologies and is supported by software and hardware development tools that help developers optimize solutions according to their unique application requirements.

The difference between the two models unveiled for the first time in this series, the ADuCM3027 and ADuCM3029, lies in their flash memory capacity (128K and 256K, respectively). Receiving a high ULPBench™ score of 252 from the independent industry alliance EEMBC (Embedded Microprocessor Benchmark Consortium), these products deliver superior performance compared to other general-purpose processors. The 32-bit ARM® Cortex®-M3 processor is easy to configure to achieve the right balance between performance and power, while also providing critical security and reliability performance.

The combination of hardware and software protection mechanisms enables faster encryption and provides read protection, preventing unauthorized users from reading the contents stored on the device. Additionally, in-circuit write protection is provided to prevent the device from being reprogrammed by unauthorized code. Stability is also enhanced by preventing damage that could cause malfunctions or system failures through voltage monitoring in standby mode and error correction for flash memory.
