8051 Program Counter Bit Width
The Program Counter (PC) is a special register within the 8051 microcontroller's CPU. Its function is to store the memory address of the next instruction that the processor will fetch and execute.
The standard 8051 architecture is designed with a 16-bit Program Counter.
This 16-bit size enables the PC to point to any location within a $2^{16}$ byte address space, translating to 65,536 unique addresses (64KB). This is essential for accessing the program instructions stored in the microcontroller's memory.
Thus, the program counter in the 8051 is 16 bits wide.
