The chipset, which was made of four individual chips included the [[/4004|4004]] CPU, the first commercial microprocessor. MCS-4 was completed by March 1971, entered production in June, and introduced into the market on November 15, 1971. |

Federico developed several design innovations at Intel that made it possible to fit the microprocessor in one chip, including new methodology for random logic chip design using silicon gate technology<ref>Faggin. Il padre del chip intelligente, Angelo Gallippi, 2002, 88-7118-149-2</ref>. Faggin developed the 4004 testing tool, chip and logic design concurrently with the layout of all the chips of the entire MCS-4 system. |

− | + | In November of 1971, a memory chip manufacturer by the name of [[Intel]] publicly announced the world's first single chip microprocessor, in the Nov. 15 issue of [[Wikipedia:Electronic News|Electronic News]]. The prophetic ad read: ''"Announcing a new era in integrated electronics"''. The chip was designed by Federico Faggin, Ted Hoff and Masatoshi Shima; it received U.S. Patent [http://www.google.com/patents/US3821715 #3,821,715]. The original 4004 chips were shipped in a 16-pin ceramic [[Dual in-line package|DIP]]. | |
