AMD Am2900
AMD Am2900 microprocessor technical specifications
Developed by: AMD
Launched: 1975
ALU bits: 4
The AM2901 is a 4-bit slice microprocessor using bipolar Schottky technology. It is designed for building high-speed microprogrammable controllers, with a number of bits that is a multiple of four.
It was designed to be used as modular components, each representing a different aspect of the CPU.
Complex problems required circuits with multiple AM2901s.
Its computing power exceeded that of monolithic microprocessors of the time by 10 times when used in well-optimized circuits.
The AM2901 became an industry standard, manufactured by Thomson, Philips/Signetics, and Fairchild, among others. It was also manufactured using CMOS and FAST technologies.
Its main competitor was the inexpensive, much lower-powered Texas Instruments SN 74S181.
