Zilog is an American semiconductor company founded by former Intel engineer Federico Faggin in 1974. Its headquarters is located in San Jose, California. After its establishment, the company rapidly gained prominence in the field of microprocessors. Its most notable achievement was the launch of the revolutionary Z80 microprocessor in 1976. This 8-bit CPU, with its outstanding performance, reasonable price, and excellent software compatibility, not only became the core of numerous home computers and game consoles at that time, but also established a long-term dominant position in industrial control and embedded systems, becoming one of the most influential and longest-lasting architectures in the history of microprocessors, and profoundly influencing the development of early personal computing and automation industries.
