32-Bit SAM Microcontrollers

Microchip Technology 32-Bit SAM Microcontrollers, powered by Arm® Cortex® CPUs, provide a unique combination of performance, power efficiency, and design flexibility. SAM MCUs 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.
