ARM Based Microcontrollers

ARM based Microcontrollers (MCU) contain a 32-bit wide data bus. They are the brain of an embedded system, a computer scaled down to a single compact chip for managing a specific operation. MCUs are highly integrated single chips with a processor, memory, I/O Peripherals, timer/counter and communication ports all contained within. The Processor present in the MCU is the core/CPU which decides the functioning of an MCU. ARM MCU is developed by ARM Holdings that contains an ARM processor core developed based on Advanced RISC Machine (ARM) architecture with32-bit RISC (reduced instruction set computer) instruction set in it. ARM cores include Cortex, SecurCore, and Mali.
