80286         
Intel 80286         
<processor> (Or "286", "i286") A microprocessor developed by Intel. THe 80286 processor has a 16-bit data bus and incorporates a memory management unit that allowed a limited amount of multitasking. The 80286 only has a segmented MMU while the later processors add a paged MMU "behind" the segmented one. The 80286 was the processor in the IBM PC AT {personal computer}. (1995-02-21)

Intel 80286

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. The 80286 used approximately 134,000 transistors in its original nMOS (HMOS) incarnation and, just like the contemporary 80186, it could correctly execute most software written for the earlier Intel 8086 and 8088 processors.

The 80286 was employed for the IBM PC/AT, introduced in 1984, and then widely used in most PC/AT compatible computers until the early 1990s. In 1987, Intel shipped its five-millionth 80286 microprocessor.
