• Microprocessors: Happy 40th birthday - 11/15/2011 - Electronics Weekly

  40 years ago today, Intel Corporation introduced the 4004, the world's first commercially available microprocessor. The 2,300 transistor device was made on a 10µm process in 1971 for Japanese calculator firm Busicom. From there came the 8008, the 8080, and then the x86 processors that are still Intel's bread and butter today, and the influential Z80. Federico Faggin designed the chip at Intel, from the architecture of Dr Ted Hoff and Stanley Mazor. Dr Masatoshi Shima of Busicom wrote the functional description and designed its logic.
