This is a summary document. A complete document is available on our Web site at www.microchip.com

The SAM is a series of low-power microcontrollers using the 32-bit ARM Cortex -M0+ processor, and ranging from to 64-pins with to 256KB Flash and 32KB of SRAM. The SAM D21 operate a maximum frequency of 48MHz 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, Event System for inter-peripheral signaling, and support for capacitive touch button, slider and wheel user interfaces.
