8051 has 40 pins, it is also called as DIP (dual inline package) because the chip contains one side 20 pins another side 20 pins that's it is called as DIP, with four ports P0, P1, P2, P3 and it has two 16 bit registers PC & DPTR.

MC has two 16-bit register (PC AND DPTR) with 40-pin's and 4 port's p0, p1, p2 and p3 respectively.

The micro-controller has two 16 bit registers i.e. program counter and the data pointer.the 8051 has 40 pins,in which 32 i/o pins and 8 are the non mask able pins.

I want to know the pin configuration of 8051 mc. i.e., how many pins it has.

These are the PC and DPTR, each is used to hold the address of a byte in a memory.

PC: holds the memory address of the next instruction. It gets incremented after every instruction.

DPTR: is made up of two 8 bit registers named DPH and DPL. It is used in operations regarding external RAM mostly.
