Working Principle of ATMEGA644PV-10MQR

The working principle of the ATMEGA644PV-10MQR is based on the classic Von Neumann architecture. This architecture consists of an instruction decoder and execution unit, a program and data memory space, external memory, and I/O pins. The instruction decoder executes instructions from the program memory, and data is stored in the data memory. External memory is used to store larger amounts of data, such as images, whereas the I/O pins can be used to directly control external devices.

The instruction decoder reads the program memory and decodes the instructions from it. The execution unit then carries out the corresponding operations and stores the results in the data memory. In addition, the microcontroller can use the external memory and I/O pins for additional operations such as image processing, communication, and machine control.
