Detailed discussion on the basic knowledge of single chip microcomputer application

A single-chip microcomputer is a single-chip microcomputer that integrates the main functional components of a microcomputer on a single chip. If you say that a single-chip microcomputer is a computer, you may not agree. In fact, it is essentially the same as the computer we use, the only difference is 5 steps and 100 steps. A single-chip microcomputer is also called a single-chip microcontroller. It is not a chip that completes a certain logical function, but a computer system integrated into a chip.

MCU composition:

A single-chip microcomputer is a system that has a CPU and program memory, data memory, input/output interface circuits, timer/counters, interrupt controller, analog/digital converter, digital/analog converter, modem and other components on a single integrated circuit chip.

The difference between a microcontroller and a single board computer:

The biggest difference between a microcontroller and a single-board computer lies in the system composition.

In terms of hardware scale, a single-chip microcomputer is equivalent to combining the resources of a basic-scale single-board computer on a single chip, so it has a considerable scale.

In terms of functionality, microcontrollers have surpassed single-board computers.

In terms of instruction system, if we compare the instruction system of the MCU with that of the Z80, except that the data transmission capability of the MCU is a little weaker, the instruction system of the MCU has greatly surpassed that of the Z80.

In addition, whether in terms of cost performance, size, or weight, the microcontroller is much superior to the single-board computer.

Classification of MCU application system:

According to the MCU system expansion and system configuration, the MCU application system can be divided into the minimum application system, the minimum power consumption system, the typical application system, etc.

Application system features:

As long as some necessary expansion circuits and channel interfaces are added to the periphery of the microcontroller, various application systems can be constructed, such as industrial control systems, data acquisition systems, automatic control systems, automatic testing systems, detection and monitoring systems, intelligent instruments, functional modules, etc.
