Working Principles

The DSPIC33FJ256GP710AT-I/PF operates based on a modified Harvard architecture. It combines the benefits of both Harvard and Von Neumann architectures, allowing simultaneous access to program memory and data memory. The CPU executes instructions fetched from the Flash memory, while data is stored in the RAM.

The microcontroller follows a fetch-decode-execute cycle, where it fetches an instruction from memory, decodes it to determine the operation, and then executes the instruction. This cycle repeats continuously, enabling the microcontroller to perform complex control algorithms and respond to external events in real-time.
