Working Principle

The working principle behind the PIC16C620-20/SO is based on the Harvard Architecture. In this architecture, the chip is divided into two parts: the instruction memory and the data memory, where each part operates in its own space. The instruction memory, also known as program memory, stores commands, instructions and algorithms, while the data memory is used to store data such as variables and static values. Both memories are connected via a common address and data bus.

In this architecture, the processor\'s internal instruction fetch unit generates an address, which is used to access the instruction memory. Then, the instruction is read and decoded, and the resulting instruction code is sent to the processor\'s execution unit. The execution unit fetches the required data from the data memory and then performs the relevant computation using an arithmetic logic unit (ALU). Once the computation is done, the processor stores the result in the data memory and performs the next instruction.
