The intel 80286 (also marketed as the iapx 286 and often called intel 286) is a 16-bit microprocessor that was introduced on february 1, 1982 it was the first 8086 based cpu with separate, non- multiplexed address and data buses and also the first with memory management and wide protection abilities. When in 1978 intel marketed the 8086 16-bit microprocessor could not imagine the success that this new chip would encounter in protected mode, it works like the 80286, enabling multitasking, protection, and virtual memory management, while also allowing for pagination. 2 2102440 introduction to microprocessors 3 80286 microprocessor ¾announced in 1982, the 5th of i86 family ¾125k transistors, hmos iii technology ¾two mode of operations zreal mode – operates as fast 8086/8088 zprotected mode – enhances memory management, multitasking and protection ¾improves both hardware and software zadditional pipeline, demultiplexed address and data.
