Four Product Series for a Broad Range of Design Needs

 

The Atmel® SAM D family is designed for easy migration within the Atmel MCU portfolio. The Atmel SAM D family consists of four pin- and code-compatible product series and a total of 35 different microcontrollers. They all use the same processor, bus matrix, interrupt system, and other core features. They are differentiated in regards to pin counts, memories, and of peripheral mix. Devices are compatible across pinouts for drop-in replacement and are code-compatible. If you need more performance or larger Flash memory, the Atmel SAM4L based on the ARM® Cortex®-M4 core is upwards-compatible with the Atmel SAM D10, SAM D11, SAM D20, and SAM D21.
