N80C286-20 was a member of AMD's Am286 family specifically designed for embedded applications, likely battery-powered. These chips were remade by AMD in static CMOS design (as opposed to nMOS), resulting in considerably lower power dissipation. This MPU was rated to operate at 20 MHz and was packaged in a 68-pin Plastic Leadless Chip Carrier package. This model was AMD's fastest 80286 processor.
