How do they work? Mini Microcontroller tutorial

Microcontrollers are small, self-contained computer systems that combine a single chip’s processor, memory, and input/output peripherals. They are designed to execute specific tasks and interact with external devices. Understanding how microcontrollers work involves examining their architecture and the embedded system’s flow of data and instructions.

Here is a simplified explanation of how microcontrollers work:

Central Processing Unit (CPU):

The CPU is the microcontroller brain . It executes instructions and performs calculations. It comprises an Arithmetic Logic Unit (ALU), a control unit, and registers. The ALU performs arithmetic and logical operations. The control unit manages the instructions and data flow.


Microcontrollers have different types of memory:

  • Read-Only Memory (ROM): ROM contains the program or firmware that is permanently stored and cannot be modified during normal operation.
  • Random-Access Memory (RAM): RAM is temporary data storage during program execution. It allows fast read and write operations but loses its contents when power is removed.
  • Flash Memory: Flash memory is nonvolatile and stores the user’s program. It can be rewritten and retains data even when power is disconnected.

Input/Output (I/O) Peripherals:

Microcontrollers have various I/O peripherals to interact with the external world. These include digital and analog input pins, output pins, communication interfaces (UART, SPI, I2C), timers, counters, and interrupt controllers. These peripherals allow the microcontroller to read from sensors, control actuators, communicate with other devices, and manage timing and events.

Program Execution:

Next, a compiler compiles the program into machine code specific to the microcontroller architecture. Finally, the compiled source code is uploaded or flashed onto the microcontroller’s memory, usually programmed using a programming tool or development environment.

During program execution, the CPU fetches instructions from the memory and executes them sequentially. It follows a Fetch-Decode-Execute cycle:

  • Fetch: The CPU retrieves the next instruction from the program memory.
  • Decode: The CPU decodes the instruction to understand what operation needs to be performed.
  • Execute: The CPU performs the instruction, which may involve calculations, data manipulation, or interactions with I/O peripherals.

Interfacing with Peripherals:

Microcontrollers communicate with external devices through their I/O pins and communication interfaces. For example, to control hardware read data from a sensor, the microcontroller configures the appropriate input pin, reads the voltage or digital signal, and processes the data accordingly. Similarly, to control an actuator like an LED or a motor, the microcontroller configures the output pin and sets the appropriate voltage or signal.

Microcontrollers use timers and interrupts to manage timing and respond to external events. Timers enable precise timing operations, such as generating accurate delays or controlling PWM signals. Interrupts allow the microcontroller to pause the program flow, handle time-critical events, or respond to external triggers.

Overall, microcontrollers execute instructions stored in their memory, interact with peripherals to gather input and control output, and run programs designed to perform specific tasks. Combining processing power, memory, and I/O capabilities makes microcontrollers versatile and suitable for various applications.
