RUS-IC

A Soviet MSI nMOS chip made in 1977, part of a four-chip calculator set designed in 1970. Early USSR made integrated circuit. The tiny block of semiconducting material (the "die"), is enclosed inside the round, metallic case (the "package").

The ideaEdit

A type of Soviet calculator IC. The Soviet Ministry of Electronics Industry (KNIIMP) ordered the creation in 1970 of the first Soviet and Europe 4 chip calculator based on large-scale integrated circuits MOS technology which was it's self based on a dynamic (clocked) with integration keys making up to 500 transistors integrated on to a single chip. It was relitvly cheep by Western prices, but painfuly exspensive for Soviets.

ManufacturingEdit

N\A, but probably akin to then Western practices.

StatsEdit

Soviet MSI nMOS chip.
Category. Statistic.
Designed in. 1970.
Made in. 1977.
Transistors per chip. 500.
Power supply. Unknown battery power voltage.
Still in use. It is now retired, but survives in some left over Soviet era stuff.
Nationality. Soviet.

Soviet microchips were originally rip-offs of Western types, but they were designing the own types by the 1980s. Armenian types were the leading type in the USSR for speed, power consumption, accuracy and efficiency by the fall of communism.

CasingEdit

A metal can with epoxy inside sits over the IC that is on a epoxy pad. The legs are metal and attached to the IC with thin gold wires. Some were fully encaced in epoxy resin.
