The 4040 is a 4- bit - microprocessor from Intel and is the successor of 4004 .
It was produced from November 1974 to 1981. The processor is compatible with its predecessor. The instruction set was expanded to 60 instructions, the program memory doubled to 8 kB and the number of 4-bit registers increased from 16 to 24. The stack for calling subroutines has been expanded to seven entries. As a further innovation, interrupts are possible.
