Working Principle of PIC12F1822T-I/RF

The main component of PIC microcontrollers is the CPU, which is responsible for executing the instructions. The rest of the microcontroller consists of memory and other peripheral components, such as the Timer, ADC (Analog-Digital Converter), I2C, SPI (Serial Peripheral Interface) and PWM (Pulse Width Modulation).

The CPU is responsible for executing the instructions stored in the program memory. The instructions are stored as a sequence of numerical codes. When the CPU executes an instruction, it looks up the code that corresponds to the instruction, then executes the instruction using the code.

The peripheral components of a PIC microcontroller are responsible for the various tasks that the microcontroller is expected to carry out. For example, the ADC is used to read analog signals and convert them into digital data for further processing. Similarly, the PWM module is responsible for generating analog signals from digital data. The other peripheral components are responsible for tasks such as reading or writing data from or to memory, or transferring data from one device to another through I2C or SPI.
