AMD Am2900

Am2900 is a family of integrated circuits (ICs) created in 1975 by Advanced Micro Devices (AMD).

They were constructed with bipolar devices, in a bit-slice topology, and were designed to be used as modular components each representing a different aspect of a computer control unit (CCU).

The Am2901 chip included an arithmetic logic unit (ALU) and 16 4-bit processor register slices, and was the "core" of the series.

In the Soviet Union and later Russia the Am2900 family was manufactured as the 1804 series (with e.g. the Am2901 designated as KR1804VS1 / Russian: КР1804ВС1)[2][3][4] which was known to be in production in 2016.
