have a standardised architecture

that allows engineers to easily port their code between different microcontroller series. 

are designed to be energy efficient which makes them ideal for portable devices that run on batteries, such as smartphones, laptops, and tablets etc.

generate less heat than other

processors, which can help extend battery life. 

are generally less expensive to

manufacture, which can lead to cheaper devices and

have a rich ecosystem of silicon

vendors and software and hardware tool providers.
