The Intel 80186 Processor
The 80186 microprocessor was developed by Intel in 1982. It is an improved 8086 with several common support functions built in: clock generator, system controller, interrupt controller, DMA controller, and timer/counter. It also added 8 new instructions and executes instructions faster than the 8086. As with the 8086, it has a 16-bit external bus and is also available as the 80188, with an 8-bit external data bus. The initial clock rate of the 80186 and 80188 was 6 MHz. They were, and still are, generally used as embedded processors.

Intel A80C186CPICE Sample Back Side
An 80186 sample chip - I do not know the background of this chip, but it seems to be a development sample for the 80186. It has a lot more pin contacts than a regular i80186, maybe some of them are unused and some provide signals for testing and evaluation.

An engineering sample of an embedded version of the i80C186 in a PQFP package with 156 contacts. I don't have any information on the clock rate or if this version ever made it into production - if you got more information on this chip please contact me.
