Federico Faggin knew well the kind of money and man-hours it took to market a microprocessor. While at Intel, he had contributed to the designs of two seminal specimens: the primordial 4004, and the 8080, of Altair fame. So when he founded Zilog with former Intel colleague Ralph Ungermann, they decided to start with something simpler: a single-chip microcontroller."
