SAM D21 Microcontroller Series

Microchip's Atmel SMART™ SAM D21 is a series of low-power microcontrollers using the 32-bit ARM® Cortex®-M0+ processor

Image of Atmel's SAM D21 MicrocontrollersMicrochip's Atmel SMART SAM D ARM® 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. The Atmel SMART™ SAM D gives you a truly differentiated general-purpose microcontroller that is ideal for many low-power, cost-sensitive industrial and consumer applications.

The Atmel SMART™ SAM D21 is a series of low-power microcontrollers using the 32-bit ARM® Cortex®-M0+ processor, and ranging from 32- to 64-pins with up to 256 KB Flash and 32 KB of SRAM. The SAM D21 devices operate at a maximum frequency of 48 MHz and reach 2.46 Coremark/MHz. They are designed for simple and intuitive migration with identical peripheral modules, hex compatible code, identical linear address map, and pin compatible migration paths between all devices in the product series. All devices include intelligent and flexible peripherals, Microchip event system for inter-peripheral signaling, and support for capacitive touch button, slider, and wheel user interfaces.
