Working Principle

The ATSAMD21G16A-MF is based on ARM Cortex-M0+ processor, which is a 32-bit low-power processor. The processor core is responsible for fetching, decoding and executing the instructions that have been stored in the program memory. The program memory can be up to 128 Kbytes of Flash memory, which is sufficient for many embedded applications.

The ATSAMD21G16A-MF also offers up to 8 Kbytes of RAM, which is used to temporarily store data and program code that has been fetched from the program memory. The RAM is used to execute instructions that the processor core has fetched from the program memory, and it is also used to store values that the processor core needs to process results. The RAM can also be used for programs that require more memory than is available in the program memory.

In addition to the processor core and RAM, the ATSAMD21G16A-MF also offers a variety of I/O interfaces. There are 32 general-purpose I/O pins that can be used to read input signals from external sensors or output signals to other devices. The ATSAMD21G16A-MF also features a counter/timer module, which can be used to measure time or frequency of events, and a variety of other peripherals, such as an ADC, PWM, I2C, SPI, and UART.

The ATSAMD21G16A-MF is programmed using ARM’s Cortex-M assembly language or C programming language, which are widely used and supported. There are several development tools available for programming the ATSAMD21G16A-MF and a wide range of third-party libraries and frameworks for making development quicker and easier.
