Dallas Semiconductor was an American manufacturer of integrated circuits (IC). The company was founded on February 1, 1984 and was acquired by Maxim Integrated in 2001 . The company's headquarters was in Dallas in the US state of Texas . The production facilities, which included class 1 clean rooms and connected wafer production , were located in the north of Dallas on an area of 22,000 m 2 . Sales in 1989 were $ 82 million.
Dallas Semiconductor became famous for its battery-backed real - time clocks with built-in NVRAM , known colloquially as the " Dallas chip ". This personal computer in the 1990s, such as the IBM Personal Computer / AT , real time clocks used had a special feature, the backup battery for data storage in the chip package integrated. Another product was the "Dallas Key", an electronic key with a 1-wire bus, which was sold under the name iButton after the takeover of Maxim . In addition, serial number chips for product identification, digital potentiometers and temperature-stabilized crystal oscillators ( TCXO , English for Temperature Compensated Crystal Oscillator ) were manufactured.
After the takeover of Maxim, the Dallas brand and the names of the integrated circuits, which begin with the abbreviation DS , were taken over and continued to be used until 2007.
