What are the characteristics of a microcontroller?-EEWORLD

Collect

The characteristics of the microcontroller are:

(1) The memory ROM and RAM of the microcontroller are strictly distinguished. ROM is called program memory, which only stores programs, fixed constants and data tables. RAM is data memory, which is used as a work area and to store user data.

(2) Adopt a control-oriented instruction system.

(3) The I/O pins of a microcontroller are usually multifunctional.

(4) The microcontroller has strong external expansion capabilities.

(5) The microcontroller is small in size, low in cost, flexible in use, and easy to commercialize.

(6) Control-oriented, it can solve various control tasks from simple to complex in a targeted manner, thus achieving the best performance-price ratio.

(7) Strong anti-interference ability and wide applicable temperature range.

(8) Multi-machine and distributed control can be easily realized, greatly improving the efficiency and reliability of the entire control system.

51 MCU bit conditional transfer instruction

CY judgment transfer instruction JC rel JNC rel The function of the first instruction is to transfer if CY is equal to 1, and to execute in sequence if it is not equal to 1. So where to transfer to? We can understand it this way: JC label, if it is equal to 1, transfer to the label and execute. We have already

The microcontroller performs different functions by pressing a single button (long or short press)

If you want to save the IO port of the single-chip microcomputer, you can use a button to execute different subroutines by judging the pressing time. I wrote one at my leisure. It may not be concise enough, but it has all the functions. Proteus simulation can be produced. There are three kinds of button time. Short pr

MCU IO pin driving capability and pull-up resistor

The pins of the microcontroller can be controlled by programs to output high and low levels, which can be regarded as the output voltage of the microcontroller. However, the program cannot control the output current of the microcontroller. The output current of the microcontroller depends largely on the external devic

PIC microcontroller A/D conversion data storage and serial port efficiency

The data after A/D conversion of PIC microcontroller usually needs to occupy two 8-bit wide RAM units, but the storage units of PIC microcontroller are limited, so the storage units of the microcontroller cannot be effectively utilized. At the same time, it takes a lot of time to transmit data to the host computer thro
