Abstract :

PIC microcontroller like all other microcontrollers have two different kinds of memory, a non-volatile memory for storing firmware and a volatile memory for temporary data. We propose analysis of architecture of PIC16F84A and a modified architecture and op-code table for PIC16F84A to interface it with external memory in this paper. This model is developed by using VHDL, simulation results have been verified. It is observed that interfaced external memory can be used by using this model without affecting its performance.
