The 8086 was sequenced8086 used less microcode than many competitors' designs, such as the MC68000 and others using a mixture of random logic — Illustration of use of "random" describing CPU control logic and microcode and was implemented using depletion-load nMOS circuitry with approximately 20,000 active transistors (29,000 counting all ROM and PLA sites). It was soon moved to a new refined nMOS manufacturing process called HMOS (for High performance MOS) that Intel originally developed for manufacturing of fast static RAM products.Fast static RAMs in MOS technology (as fast as bipolar RAMs) was an important product for Intel during this period. This was followed by HMOS-II, HMOS-III versions, and, eventually, a fully static CMOS version for battery powered devices, manufactured using Intel's CHMOS processes.CHMOS is Intel's name for CMOS circuits manufactured using processing steps very similar to HMOS. The original chip measured 33 mm² and minimum feature size was 3.2 μm. The MUL and DIV instructions were very slow due to being microcoded so x86 programmers usually just used the bit shift instructions for multiplying and dividing instead.
