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 ==
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.
