The KR580VM80A ((ロシア語:КР580ВМ80А)) is a Soviet microprocessor, a clone of the Intel 8080 CPU. Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM1800 computer in 1979. Production ceased with the fall of the USSR. Initially called the K580IK80 (К580ИК80), it was produced in a 44-pin planar metal-ceramic (climatic) package. Later, a generic consumer version in a PDIP-40 package was produced and was named the KR580IK80A (КР580ИК80А). The pin layout of the latter completely matched that of Intel's 8080A CPU. In 1986 this CPU received a new part number to conform with a new naming scheme and became known as the KR580VM80A (КР580ВМ80А), the number it is most widely known by today. Normal clock frequency for the K580IK80A is 2 MHz, with speeds up to 2.5 MHz for the KR580VM80A. == Applications == The KR580VM80A was popular in home computers, computer terminals, industrial controllers. Some of the examples of its successful application are: * KUVT Korvet educational computer * Radio-86RK popular homebrew computer * SM 1800 industrial mini computer * Vector-06C home computer, where KR580VM80A is overclocked to 3MHz by design * TIA-MC-1 (ТИА-МЦ-1) arcade machine 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KR580VM80A」の詳細全文を読む スポンサード リンク
