KR580IK80A =/P8080A 8080 Soviet Clone 8-Bit Microprocessor MCU MPU CPU IC QTY-1 The KR580VM80A (Russian: КР580ВМ80А) is a Soviet microprocessor, a clone of the Intel 8080 CPU.[2Different versions of this CPU were manufactured beginning in the late 1970s, the earliest known use being in the SM1800 computer in 1979. Initially called the K580IK80 (К580ИК80), it was produced in a 48-pin planar metal-ceramic package. Later, a 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 the 1980 Soviet integrated circuit designation and became known as the KR580VM80A (КР580ВМ80А), the number it is most widely known by today (the KR580VV51A and KR580VV55A peripheral devices went through similar revisions). Normal clock frequency for the K580IK80A is 2 MHz, with speeds up to 2.5 MHz for the KR580VM80A. The KR580IK80A was manufactured in a 6 µm process.[3] In the later KR580VM80A the feature size was reduced to 5 µm and the die became 20% smaller.[ Please allow for the following shipping times: EU countries: 5-8 business days, on rare occasions a few days more USA: 10-15 business days, on rare occasions more South East Asia (Japan, Singapore, S.
