Analog Devices Inc. ADuCM3027 & ADuCM3029 ULP Microcontrollers
Analog Devices Inc. ADuCM3027 and ADuCM3029 Ultra Low Power (ULP) Microcontrollers (MCUs) are 32-bit Arm® Cortex®-M3 Core-based MCUs, easily configured to achieve the right balance of performance and power while still offering critical security and reliability functions. These fast MCUs offer a high ULPBench™ certified score of 245.5 points, as established by the EEMBC (Embedded Microprocessor Benchmark Consortium), an independent industry alliance. The ADuCM3027 and ADuCM3029 differ only in flash memory, offering 128K and 256LK, respectively.
Faster encryption enabled by a combination of hardware and software protection mechanisms provides 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 which could result in misoperation or system crashes.
