SAM Microcontrollers Based on Arm® Cortex®-M Cores


Create differentiated designs with our broad portfolio of SAM device families that are powered by Arm® Cortex® CPUs. These devices provide a unique combination of performance, power efficiency and design flexibility to meet the specific requirements of your project. SAM device families offer a variety of advanced peripherals that make them an excellent option for developing all kinds of 32-bit embedded applications. These peripherals include the enhanced Peripheral Touch Controller (PTC), low-power sleepwalking peripherals, the efficient Event System and a rich set of high-performance analog features.

Click on the SAM family names in our interactive diagram below to learn more and discover the right device for your next project.
