12-bit microcontroller ATSAML22 series

general purposelow-poweranalog

With the huge growth of the Internet of Things (IoT) and the widespread use of wearables and low-power accessories, designers increasingly need lower-power solutions that also offer robust security and touch interfaces. Our SAM L family of microcontrollers (MCUs) is built with innovative picoPower® technology to deliver best-in-class low power consumption down to 25 µA/MHz in active mode, under 100 nA in sleep mode and fast wake-up times of 1.2 uS. These MCUs have achieved an EEMBC-certified ULPMark™ score of 410, which is the highest score for an Arm® Cortex®-M23 or Cortex-M0+ class device. In addition to ultra-low-power capabilities, these devices feature an enhanced Peripheral Touch Controller (PTC), robust security, Arm TrustZone® technology, Advanced Encryption Standard (AES) encryption, Full-Speed USB host and device, Event System and SleepWalking, 12-bit analog, built in op amps and much more. Discover how you can use the SAM L series of MCUs to expand battery life from years to decades, add elegant touch capabilities to your product and secure your IoT nodes. Key Features picoPower Technology: Devices are designed to offer the lowest possible power consumption from transistor design and process geometry, sleep modes, flexible clocking options, on-the-fly user-selectable performance levels, Event System to SleepWalking peripherals. These devices can operate down to 1.62V while still maintaining all functionality, including analog functions. They have a short wake-up time, with multiple wake-up sources from even the deepest sleep modes. They utilize low leakage processes and libraries to deliver industry-leading low power consumption in active and all sleep modes.
