Additional Details

The AM2901CDM contains a 16-word by 4-bit two-port RAM, an arithmetic logic unit (ALU), and shifting and control logic. The ALU performs eight different functions on two 4-bit input words. Data can be shifted either left or right. Microprogramming allows for the definition of custom instruction sets, providing immense flexibility in system design. It operates with a single 5V power supply. The device is typically packaged in a ceramic DIP (Dual In-line Package).
