Programmable peripheral interface (8255) 1 Architecture of 8255 . The parallel input-output port chip 8255 is also called as programmable peripheral input- output port. The Intel’s 8255 is designed for use with Intel’s 8-bit, 16-bit and higher capability microprocessors. Interfacing is one of the important concepts in microcontroller 8051 because the microcontroller is a CPU that can perform some operation on a data and gives the output. . However to perform the operation we need an input device to enter the data and in turn output device displays the results of the operat
