IC - 40 pin DIP Microprocessor

Integrated Circuit 40 pin DIP Microprocessor

Intel 8255 (or i8255) Programmable Peripheral Interface (PPI) chip is a peripheral chip originally developed for the Intel 8085 microprocessor. Member of a large array of such chips, known as the MCS-85 Family. This chip was later also used with the Intel 8086 and its descendants. It was later made (cloned) by many other manufacturers.

The 8255 is widely used in many microcomputer/microcontroller systems, especially Z-80 based, home computers such as SV-328 and all MSX.

Also in the system board of the best known original IBM-PC,[4] PC/XT, PC/jr, etc. and clones, along with numerous homebuilt computer computers such as the N8VEM.
