The K1810VM86 (Russian: К1810ВМ86) is a Soviet 16-bit microprocessor, a clone of the Intel8086CPU with which it is binary and pin compatible. It was developed between 1982 and 1985. The original K1810VM86 supported a clock frequency of up to 5 MHz while up to 8 MHz were allowed for the later K1810VM86M (К1810ВМ86M; corresponding to Intel 8086-2). The K1810VM86 was manufactured plastic 40-pin dual in-line package (as KR1810VM86 / КР1810ВМ86) or in a 40-pin ceramic dual in-line package (as KM1810VM86 / КМ1810ВМ86 for the commercial version or M1810VM86 / М1810ВМ86 for the military version). A clone of the related Intel 8088 with its 8-bit bus was manufactured as the K1810VM88 (Russian: К1810ВМ88), also in plastic and ceramic packages.
The K1810VM86 was manufactured with an n-MOS process.
The family consists of the following chips:
For brevity, the table above lists only the chip variants in a plastic DIP (prefix КР). Not listed separately are variants in a ceramic DIP (prefix КМ for commercial version and prefix М for the military version).
Additionally, many devices in the K580 series could be used for the K1810 series as well.
