AI overview

A microcontroller is a tiny computer on a single chip that combines a processor, memory, and input/output connections all in one package, making it small enough to fit inside everyday devices. They matter because they enable the automatic control and operation of countless products we use, from household appliances to industrial equipment, without needing a full-sized computer.

A microcontroller (MC, uC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more processor cores along with memory and programmable input/output peripherals. Program memory in the form of NOR flash, OTP ROM, or ferroelectric RAM is also often included on the chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general-purpose applications consisting of various discrete chips.
