Low-power microcontrollers

23 March 2016 DSP, Micros & Memory

New from Analog Devices is the ADuCM302x series of ultra-low power ­microcontrollers designed to enable longer battery life and lower operating costs in IoT applications without sacrificing security and reliability functions.

Consuming less than 38 μA/MHz of current in active mode and less than 750 nA in standby mode, the devices nevertheless do not sacrifice key functionality to achieve efficiency benchmarks, rather maintaining a full suite of reliability and safety functions.

The ADuCM3027 and ADuCM3029 are the initial offerings in the series, differing only in Flash memory (128 KB and 256 KB respectively). They outperform other general-purpose processors with a high ULPBench certified score of 245,5 points as established by the EEMBC (Embedded Microprocessor Benchmark Consortium), an independent industry alliance.

The 32-bit ARM Cortex-M3 processor is easily configured to achieve the right balance of performance and power while still offering critical security and reliability functions. Faster encryption, enabled by a combination of hardware and software protection mechanisms, provides read protection to prevent the device contents from being read by unauthorised users. Additionally, in-circuit write protection prevents the device from being reprogrammed with unauthorised code. Voltage monitoring in standby mode and error correction for the Flash memory increase reliability by avoiding corruptions which could result in misoperation or system crashes.
