32 Bit Microcontrollers

32-Bit 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 most important criteria in selecting a microcontroller for a particular application is the data bus width expressed in bits. Performance of MCU increases with increase in data bus width.
