AMD 80286 microprocessor

Intel licensed 80286 microprocessor to AMD in the second half of 1984. AMD's selection of 80286 microprocessors at that time was very similar to Intel's - they manufactured 286 CPUs in CLCC, PLCC and ceramic PGA packages with speed grades up to 12 MHz. In 1985 AMD followed Intel's lead and changed package type prefixes in their part numbers: "CG" was replaced with "A", "C" was changed to "R" and "J" was replaced with "N".

80286 was the last Intel microprocessor licensed to AMD. In 1987 Intel cancelled 1982 technology exchange agreement, as a result AMD didn't get rights to 80386 CPU. In 1992, after long arbitration process, AMD was awarded royalty-free rights to manufacture and sell 80386 microprocessors. Been unable to sell their own 80386 chips before that, the obvious choice for AMD was to prolong life of 80286 family by releasing faster CPU versions. 16 MHz version of the 286 CPU was released in August of 1987. Later AMD introduced 20 and 25 MHz versions of 80286.

AMD used the same naming convention for 80286 processors as Intel. Earlier processors in ceramic leadless chip carrier package were named "C80286-<frequency>". In 1985 the naming convention for CLCC processors was changed to "R80286-<frequency>". Interesting that the earlier processors (up until 1986) had AMD copyright.

68-pin ceramic PGA

Like Intel 80286 processors, early AMD processors in ceramic PGA package had the prefix "CG". In 1985, AMD started to use "A" prefix for PGA processors.

68-pin plastic LCC

Engineering sample of AMD N80L286 microprocessor. AMD 80L286 is a low-power microprocessor that operates at the same core voltage as the 80286 CPU and is fully compatible with it, but has lower power consumption. For example, 10 MHz N80L286 CPU has maximum power consumption 2 Watt, while AMD N80286-10 has maximum power consumption 3.3 Watt.
