<P> A microcontroller ( MCU for microcontroller unit , or UC for μ - controller ) is a small computer on a single integrated circuit . In modern terminology , it is similar to , but less sophisticated than , a system on a chip or SoC ; an SoC may include a microcontroller as one of its components . A microcontroller contains one or more CPUs ( processor cores ) along with memory and programmable input / output peripherals . Program memory in the form of ferroelectric RAM , NOR flash or OTP ROM is also often included on 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 . </P>
