1.3.2 Microcontroller
A microcontroller (sometimes abbreviated Β΅C, uC or MCU) is a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Microcontroller also called computer in chip. The fixed amount of on-chip ROM, RAM, and number of I/O ports in microcontroller makes them ideal for low cost and low space applications. Figure 3 shows the illustrations of inside of a microcontroller.
