The Intel 8255 (or i8255) Programmable Peripheral Interface (PPI) chip was developed and manufactured by Intel in the first half of the 1970s for the Intel 8080 microprocessor, and is a member of the MCS-85 Family of chips. The i8255 was also used with the Intel 8085 and Intel 8086 and their descendants and found wide applicabilaty in digital processing systems. It was later cloned by other manufacturers. It is available in DIP 40 and PLCC 44 pins packages. The 82C55 is a higher speed CMOS version.
The i8255 provides 24 parallel input/output lines but the functionality of the i8255 is now mostly embedded in larger VLSI processing chips as a sub-function. The i8255 is still made, and is often used to expand micro controller input/output.
