Produced From 1978 to 1990s
Common manufacturer(s)
Intel, AMD, NEC, Fujitsu, Harris (Intersil), OKI, Siemens AG, Texas Instruments, Mitsubishi.
Max. CPU clock rate 5 MHz to 10 MHz
Min. feature size 3μm
Instruction set x86-16

Successor 80186
Package(s)
40 pin DIP
Variant 8088
The 8086[1] (also called iAPX 86) is a 16-bit microprocessor chip designed by Intel between early 1976 and mid-1978, when it was released. The 8086 gave rise to the x86 architecture of Intel's future processors. The Intel 8088, released in 1979, was a slightly modified chip with an external 8-bit data bus (allowing the use of cheaper and fewer supporting logic chips[2]), and is notable as the processor used in the original IBM PC.

History
Background
In 1972, Intel launched the 8008, the first 8-bit microprocessor.[3] It implemented an instruction set designed by Datapoint corporation with programmable CRT terminals in mind, that also proved to be fairly general purpose. The device needed several additional ICs to produce a functional computer, in part due to it being packaged in a small 18-pin "memory-package", which ruled out the use of a separate address bus (Intel was primarily a DRAM manufacturer at the time).
Two years later, Intel launched the 8080,[4] employing the new 40-pin DIL packages originally developed for calculator ICs
