It is an IC ie. 8255. it is used with in a combination with a microprocessor for the application of complex control algorithms. it is used coz of incapability of a micro-controller to achieve the same.....

What is the alternativwe needs in 82c55 if it is not available?

If the 82C55 programmable peripheral interface is not available, alternative options include using other programmable I/O chips like the 8255 PPI or microcontrollers with built-in I/O capabilities, such as those from the PIC or AVR families. Additionally, using GPIO (General Purpose Input/Output) pins on a microcontroller can fulfill similar functions, allowing for flexible control of peripherals. In some cases, FPGA (Field-Programmable Gate Array) solutions may be used to replicate the functionality of the 82C55.
