MA2901
RADIATION HARD 4-BIT MICROPROCESSOR SLICE
The MA2901 is an industry standard 4-bit microprocessor slice It provides a set of ALU functions selected by microcode data applied to the inputs. The device is cascadable to handle any word length. It can be used as a building block in the construction of microcomputers and controllers tailored to meet specialised applications.
Dual Address Architecture Machine cycles are saved by simultaneous, independent access to two working registers.
ALU has Eight Functions Operations performed are addition, two subtractions and five logic functions on two source operands.
Four State Flags Zero, negative, carry and overflow.
Left / Right Shift is Independent of ALU Only one cycle taken for add and shift operations.
