The (redesigned) [[CMOS]] version, 80C186, introduced [[DRAM refresh]], a power-save mode, and a direct interface to the 80C187 floating-point numeric [[coprocessor]]. Intel [[second-source]]d this microprocessor to [[Fujitsu]] Limited around 1985.<ref>Intel Corporation, "NewsBits: Second Source News", Solutions, January/February 1985, Page&nbsp;1.</ref> Both packages for Intel 80186 version were available in 68-pin [[Plastic leaded chip carrier|PLCC]] and [[Pin grid array|PGA]] in sampling at third quarter of 1985.<ref>Ashborn, Jim; "Advanced Packaging: A Little Goes A Long Way", Intel Corporation, Solutions, January/February 1986, Page&nbsp;2.</ref> The 12.5&nbsp;MHz Intel 80186-12 version using the [[1.5 μm process|1.5&nbsp;μm]] [[Depletion-load NMOS logic#Intel HMOS|HMOS-III]] process for US$36 in quantities of 100.<ref>Intel Corporation, "New Product Focus Component: 80186-12 Microprocessor: Fast And Formidable", Solutions, March/April 1986, page&nbsp;10.</ref> The 12.5&nbsp;MHz Intel 80C186 version using the [[CHMOS]] III-E technology using approximately 90&nbsp;mA under normal load and only 32&nbsp;mA under power-save mode. It was available in 68-pin PLCC, [[Pin grid array#Ceramic|CPGA]], or CLCC package.<ref>Ormsby, John, Editor, "New Product Focus: Components: It's Under Control With The 80C186", Intel Corporation, Microcomputer Solutions, November/December 1987, page&nbsp;13.</ref>

The M80C186 military version was available in 10 and 12&nbsp;MHz versions. They met [[MIL-STD-883]] Rev.&nbsp;C and [[MIL-STD-1553]] bus application standards. The 12&nbsp;MHz CHMOS version consumes approximately 100&nbsp;mA. The available packages were 68-pin CPGA and [[Quad flat package|CQFP]]. The 10&nbsp;MHz M80C186 PGA version was available for US$378 in 100-unit quantities.<ref>Intel Corporation, "Focus: Components: Fast M80C186 Embedded Controller Cuts Power Usage", Microcomputer Solutions, March/April 1989, page&nbsp;12.</ref>

The 80C186EB was a fully static design for the [[application-specific standard product]] using the [[1 μm process|1&nbsp;μm]] CHMOS IV technology. They were available in 3- and 5-volt versions with 84-lead PLCC and 80-lead [[EIAJ]] [[QFP]] packaging. It was also available for US$16.95 in 1,000-unit quantities.<ref>Intel Corporation, "New Product Focus: Components: New ASSP Suits Mobile Applications", Microcomputer Solutions, September/October 1990, page&nbsp;11.</ref>

The Intel 80C186EC contains 4 DMA channels, 2 interrupt controllers, 22 I/O which control two serial channels, and 4 timers. This version was available for US$17.70 in quantites of 1,000 units. This microcontroller only available in 5-volt version. Both Intel 80C186EC and 80C186EA contains three different power-management modes, which has idle, powerdown and powersave. The 80C186EA has both 5- and 3-volt versions.

The 80C186XL version was available up to 20&nbsp;MHz, which is compatible with existing CMOS version of 80C186 that has 25% higher performance and 50% lower power consumption. This version used 1&nbsp;μm CHMOS process technology. Both 80C186EA and 80C186XL were available for US$11.80 in quantities of 1,000 units.<ref>Intel Corporation, "New Product Focus: Components: Processors Provided More Functions for Embedded Applications", Microcomputer Solutions, November/December 1991, page&nbsp;13.</ref>
