CPU ( Central Processing Unit )

An 8-bit CPU at the heart of the microcontroller executes commands extremely well. It has a wide range of registers, enabling flexible data manipulation and control flow.

Memory

Program Memory: The CPU fetches and executes the programme code that is stored in the flash memory. Even complicated programmes can be supported by the 32KB capacity.

Data Memory: SRAM and EEPROM are the two forms of data memory used by the ATmega328P. While EEPROM offers non-volatile storage for crucial data that must endure through power cycles, SRAM offers volatile data storage.

Input/Output Ports

The microcontroller’s interface with the outside world is represented via its pins. These pins can be set up as inputs or outputs, which enables a variety of uses, including reading sensors and driving LEDs.

Timers and Counters

In many embedded systems, precise timing is essential. Three timers are available on the ATmega328P, each with special qualities that make them useful for different applications. These timers are frequently used to produce precise PWM signals to control motors, among other things.

Communication Module ( USART )

By enabling serial communication, the USART modules allow for communication with external hardware, including sensors, displays, and other microcontrollers.

Analog to Digital Converter

For situations where the transformation of analogue signals into digital data is necessary, the ADC is an invaluable component. Sensor interfacing and data gathering systems frequently make advantage of this functionality.

This is the Architecture of ATmega328 Microcontroller. In the above notes, we are discuss about the each and every block of the architecture of atmega328 microcontroller.
