Advanced Micro Devices (AMD) had a number of product lines with the part numbers beginning with "29". These families were generally not related to one another.

The Am29(F, BL, DL, DS)xxx family contains a variety of flash memories, and is not part of the Am2900/Am29000 families.

Am2900 Family[edit]

The first such family is the Am2900 series of integrated circuits (ICs) created in 1975 designed in bit-slice topology so they could be used as modular components each representing a different aspect of a computer control unit (CCU). For details on the Am2900 Family see The Am2900 Family Data Book, by AMD.
