It is designed for the cost-sensitive embedded applications that require very low power consumption and maximum reliability. This microcontroller is suitable for a variety of applications such as data gathering, automation, audio, white goods control, medical, energy management and more.

ATSAMD21G16A-AUT belongs to the family of Microcontroller of embedded system. Microcontroller are miniature computers and are referred to as embedded controllers because they are designed for specific task of an embedded system. They are integrated circuits that consist of a processor, boot and sleep code memory, write protected memory, work RAM, clock circuits, interrupt logic, I/O ports and other functional units.

The ATSAMD21G16A-AUT incorporates the ARM Cortex-M0+ cores. ARM Cortex-M0+ is a low-cost, low-power, 32-bit microcontroller architecture developed by ARM with a wide range of peripheral resources. The Cortex-M0+ processor implements a Harvard architecture, which allows for separate instruction and data buses, as well as multiple levels of memory. The Cortex-M0+ also provides bit- and bit-field instruction set extensions and higher-performance extensions such as single-cycle multiply-accumulate and bit-counting instructions. The Cortex-M0+ core can also support an optional memory protection unit, and provides low power operation through 32-bit wake-up and low sleep states. The Cortex-M0+ also includes an exception handling unit, with support for the ARMv6-M vector table.

ATSAMD21G16A-AUT contains 4KB of instruction cache, 4K database buffer, up to 8KB of system RAM and 32K of user data EEPROM. It provides up to 8 channels of 8-bit PWM with hardware dithering and up to 8 channels of 8-bit ADC with selectable gain. It also provides enhanced back-biasing functionality in the analog-to-digital converter which allows reduced power consumption and wide dynamic output range. Furthermore, the device integrates a 32-bit Cyclic Redundancy Check (CRC) hardware accelerator for efficient and reliable data-integrity checking.
