The Intel '''80186''', also known as the '''iAPX 186''',<ref name="i286">{{cite book|url=http://bitsavers.org/components/intel/80286/210498-001_iAPX_286_Programmers_Reference_1983.pdf|title=iAPX 286 Programmer's Reference|at=page 1-1|publisher=Intel|year=1983}}</ref> or just '''186''', is a [[microprocessor]] and [[microcontroller]] introduced in 1982. It was based on the [[Intel 8086]] and, like it, had a [[16-bit]] external [[Bus (computing)#Address bus|data bus]] multiplexed with a 20-bit [[address bus]].  The '''80188''' variant, with an [[8-bit]] external data bus was also available.
