What are ARM MCUs? 

An MCU (Microcontroller Unit) is an intelligent semiconductor IC (Integrated Circuit) that consists of a processor unit, memory modules, communication interfaces and peripherals.

ARM means Advanced RISC (Reduced Instruction Set Computer) Machine. ARM architecture is the most commonly used 32-bit instruction set architecture, there are 16-bit and 64-bit support options available too. ARM architecture is used on Windows, Apple iOS, Android, Linux and more. Arm ltd created the architecture and licenses it to other companies.
