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, and 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. An 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.
