AMD Integrated Circuits286 MicroprocessorFeatured in the digital image below is the corner of a packaged AMD 286 microprocessor revealing bonding wires attached to the pad ring and a large cache area. The chip was obliquely illuminated with yellow and green filters to enhance surface features and was imaged utilizing differential interference contrast (DIC) optical techniques coupled to reflected light optical microscopy. The Advanced Micro Devices (AMD) 286 microprocessor, fabricated and distributed under license from Intel, utilizes identical architecture and the source code developed for the i80286 chip. AMD boosted Intel's original 6, 10, and 12 megahertz clock speed versions, which are powered at 5 volts, to standard models featuring higher speeds ranging up to 20 megahertz. During the mid-1980s, AMD launched the microprocessor clone market with their 286A processor, which followed their in-house version of the 287 math coprocessor. Released in 12 and 16 megahertz clock speeds, the 286A model did not break new ground, but did feature expanded memory specifications (EMS) and the ability to reassume protected mode, neither which was supported by the Intel 286.
