The principal behind the working of a PIC16F872-E/SP microcontroller is quite simple. The microcontroller contains a central processing unit (CPU), on-chip memory, and peripherals that are used to carry out its task. The CPU is responsible for the main processing tasks and can access the memory and peripherals through the on-chip bus architecture. The CPU uses its instruction set to control the peripherals, read and write data to and from memory, and execute programs stored in memory. The program counter is used to keep track of the current instruction being executed, and the stack pointer is used to keep track of the current position in the stack, or data. The internal program counter is used for branching and looping operations. When external peripherals are used, a set of control registers is used to control the flow of data and timing between the CPU, memory, and peripherals.

The PIC16F872-E/SP microcontroller is quite powerful and uses a large number of features in a small package. This makes it well suited for a variety of embedded applications, such as motorized devices, telemetry and tracking systems, home automation, security systems and medical equipment.
