New Benchmark in Flexibility and Ease-of-Use based on
ARM® Cortex® Microcontrollers

SAM D MCUs give you truly differentiated general-purpose microcontrollers that are ideal for many low-power, cost-sensitive industrial and consumer applications. The MCUs offer excellent interface and peripheral options with impressive low power–performance.  



Microchip SAM D Cortex®-M0+ based microcontroller (MCU) series builds on decades of innovation and experience in embedded Flash microcontroller technology. It not only sets a new benchmark for flexibility and ease-of-use but also combines the performance and energy efficiency of an ARM Cortex-M0+ based MCU with an optimized architecture and peripheral set.

  • Cortex-M0+ based MCU running up to 48MHz
  • Flash memory densities range from 8KB to 256KB with SRAM ranging from 2KB to 32KB
  • Low power consumption at <70µA/MHz
  • DMA and Event system
  • Up to Six flexible serial communication modules (SERCOM) provide peripheral flexibility
  • Full-Speed USB Device and embedded Host
  • 12-bit ADC with up to 20 channels; 10-bit DAC
  • Hardware touch support with the QTouch® Peripheral Touch Controller
  • Packages ranging from 14 to 64-pin package options


The SAM D51 high performance micro-controller series features the 32-bit ARM® Cortex®-M4F processor with Floating Point Unit (FPU), running up to 120 MHz ,up to 1 MB Dual Panel Flash with ECC, and up to 256 KB of SRAM with ECC. This series offers excellent interface options with class leading power performance and integrated hardware security. 

  • ARM Cortex-M4F  core running at 120 MHz with Single Precision Floating Point Unit (FPU).
