Microcontroller Concepts

Microcontroller Concepts
Architecture: Computer architecture defines the structure and interrelationships of the components of a system, such as input/output, storage, communication, control, and processing. It also determines the capabilities and programming model of a computer, as well as the logical interface that is targeted by programming languages and their compilers.

Central Processing Unit (CPU): The CPU is like the brain of the microcontroller. It’s responsible for executing instructions and making decisions. Imagine it as the person who follows the step-by-step instructions given to them to perform specific tasks.

Instruction set: “instruction set” is like the list of commands or instructions that a computer processor or microcontroller can understand and execute. It’s the language that the central processing unit (CPU) of the computer or microcontroller speaks. some examples are – MOV (Move), ADD (Addition), CMP (Compare), B (Branch).

Register: a “register” is a small, fast storage area inside the central processing unit (CPU) that is used to store data temporarily during the execution of a program. Think of registers as tiny, super-fast storage units that the CPU can access quickly. They play a crucial role in the microcontroller’s processing of instructions and data.

Introduction to microcontrollers

Introduction to microcontrollers
A Microcontroller is an Integrated Circuit (IC) that contains electronic computing unit and logic unit (together known as CPU), Memory (Program Memory and Data Memory), I/O Ports (Input / Output Ports) and few other components integrated on a single chip.

Basically, a Microcontroller consists of the following components.

Central Processing Unit (CPU)
Program Memory (ROM – Read Only Memory/Flash)
Data Memory (RAM – Random Access Memory)
Timers and Counters
I/O Ports (I/O – Input/Output)
Serial Communication Interface
Clock Circuit (Oscillator Circuit)
Interrupt Mechanism
Peripherals like SPI (Serial Peripheral Interface), I2C (Inter Integrated Circuit), ADC (Analog to Digital Converter), DAC (Digital to Analog Converter), CAN (Controlled Area Network), USB (Universal Serial Bus), and many more.

Fundamentals of Embedded Systems
