The simplest MCU System refers to the normal operation of the microcontroller can be a peripheral component, mainly by the microcontroller, the crystal oscillator circuit and the reset circuit. The input and output through the MCU I / O port. Generally speaking, the one-chip computer application system refers to the application system that is made up of one-chip computer, peripheral interface circuit and suitable software in order to realize the particular function.
Microcontroller is the central processor (CPU), random access memory (RAM), read-only memory timer chip and some input and output interface circuit integrated microcontroller on a chip.
It can be seen from the above typical examples, the basic structure of the microcontroller system block diagram shown. As can be seen from the figure, for a typical microcontroller system, mainly by the microcontroller (CPU), crystal and reset circuit, input control, output display, peripheral functions and communication interfaces 6 parts. The main functions of each part are as follows:
