What is MCU?
Microcontroller
A microcontroller (MCU) is a single chip that integrates a processor core, memory, and peripherals, designed to run dedicated firmware for real-time control in embedded products.
The MCU is the brain of most embedded devices. Choosing the right one — balancing performance, power, peripherals, and cost — is one of the most consequential early design decisions.
