Bringing AVR Ease-of-Use to Cortex M0+ Microcontrollers

 

The Atmel® SAM D family, based on the ARM® Cortex®- M0+ core, builds on decades of innovation and experience in embedded Flash microcontroller (MCU) technology. It sets a new benchmark for flexibility and ease-of-use. It also combines the performance and energy-efficiency of the ARM® Cortex®-M0+ core with an optimized architecture and peripheral set. This general-purpose MCU family is ideal for many low-power, cost-sensitive industrial and consumer applications. With 4-pin and code-compatible product series in the SAM D Family, Atmel offers a complete product offering bringing AVR ease-of-use to 32-bit microcontrollers.
