The Intel 4040 (i4040) is a 4-bit microprocessor introduced in 1974 by Intel as a successor to the Intel 4004. The 4040, fabricated using pMOST technology, introduced a small set of additional instructions, a larger call stack, a larger register file, and interrupt capabilities. The package size was also increased to 24 pins. The 4040 is part of the Intel MCS-40 chipset.

The Intel 4040 was used in a large number of early video games and gaming machines such as the Bailey shuffleboard.

Overview[edit]

Following the success of the Intel 4004, Intel released the 4040, an enhanced version. The new chip included a much larger stack (7 levels instead of 4). The 4040 also introduced interrupt support. 14 new instructions were added and the register file was increased to 24 index registers.
