Soviet integrated circuit designation

This article describes the nomenclature for integrated circuits manufactured in the Soviet Union. [1](pp10–16) [2] The nomenclature is defined in the standard OST 11.073.915-2000 (Russian: ОСТ 11.073.915—2000), published in the year 2000. Earlier version were ОСТ 11.073.915—80 in the year 1980 and before that ГОСТ 18682—73 in 1973. 25 years after the dissolution of the Soviet Union this designation is still used by a number of manufacturers in Russia, [3] [4] [5] [6] [7] [8] Belarus, [9] [10] Ukraine, [11] Latvia, [12] and Uzbekistan. [13] The designation uses the Cyrillic alphabet which sometimes leads to confusion where a Cyrillic letter has the same appearance as a Latin letter but is romanized as a different letter. Furthermore, for some Cyrillic letters the Romanization is ambiguous.

  1. 1 2 Initially group В (V) had not yet been defined and computing devices were all assigned subgroup ИК (IK), e.g. microprocessors (КР580ИК80А), peripheral devices (КР580ИК51). With introduction of group В the devices in 580 series were renamed (to КР580ВМ80А and КР580ВВ51А, respectively) in 1986.
  2. 1 2 Initially digital signal processors were assigned subgroup ВМ (VM, e.g. 1867ВМ2). It is unclear when the new subgroup ВЦ (VTs) was added (e.g. 1867ВЦ2АТ).[7][8]
  3. 1 2 3 Even though subgroup ИА has been specified for arithmetic logic units (ALU), most ALU devices were assigned subgroups ИК (e.g. КР531ИК2) or ИП (e.g. К155ИП3, 564ИП3, КР1530ИП14).
  4. 1 2 The distinction between voltage switches (КН) and current switches (КТ) is somewhat unclear. There are analogue switches and multiplexers in both subgroups.
  5. 1 2 [1](p12) as well as [2] list subgroup ЛК as AND-OR-NOT while all known ECL devices in this subgroup are listed as OR-AND-NOT.[1](p90)[14] The equivalent Motorola devices are also listed as OR-AND-NOT, so the real devices win. The same reasoning applies to subgroup ЛС.
  6. 1 2 3 Initially FIFO and multi-port devices were included in subgroup РП. Later (sometime before 2011) they were assigned the separate subgroups РГ and РК, respectively.[8][9]
  7. 1 2 Initially subgroup РР was used for all EEPROM and Flash devices, regardless of the interface. Later (sometime before 2011) subgroup РС was introduced for devices with a serial interface and subgroup РР was limited to devices with a parallel interface.[3][8][9]
  8. 1 2 All known voltage comparators are in subgroup СА, so [1](p13) apprears to be correct while the Russian Wikipedia and [2] incorrectly list subgroup СА as amplitude comparators. Consequently, subgroup СК is for amplitude comparators.
  9. ↑ This subgroup is listed only in.[2]

Romanization

The Romanization of Russian is standardized, only there are at least 11 standards to choose from. Fortunately, the Soviet integrated circuit designation uses a subset of the Cyrillic alphabet where rather few letters are ambiguous:

The more common romanizations in bold are given as alternatives in the above tables.

It should be noted that the French romanization of Russian and the German romanization of Russian differ in some letters from the one used in English. For instance, the Russian КР580ВМ80A becomes KR580VM80A in English and French but KR580WM80A in German literature.
