Cirrus Logic
Cirrus Logic Inc. is an American fabless semiconductor supplier that specializes in analog, mixed-signal, and audio DSP integrated circuits (ICs). Since 1998, the company's headquarters have been in Austin, Texas.
The company's audio processors and audio converters feature in audio and consumer entertainment products, including smartphones, tablets, laptops, digital headsets, automotive entertainment systems, home-theater receivers, and smart home applications, such as smart speakers. The company has over 3,200 customers including Ford, Harman International, Itron, LG, Lenovo, Onkyo, Marantz, Motorola, Panasonic, Pioneer, Samsung, SiriusXM, Sony, Apple, and Vizio. Apple makes up 89% of the company's revenue in 2025.
Suhas Patil founded the company as "Patil Systems, Inc." in Salt Lake City in 1981; it adopted the name "Cirrus Logic" when it moved to Silicon Valley in 1984.
Cirrus Logic has more than 3,900 patents issued and pending.
Patil Systems, Inc., was founded in Salt Lake City, Utah, in 1981 by Suhas Patil, and in 1983 the company was reorganized by Patil, Kamran Elahian, and venture capitalist Fred Nazem, whose firm, Nazem and Company provided the company's first/start-up round of financing. Later the company was renamed as Cirrus Logic when it moved to Silicon Valley in 1984 to focus on solutions for the growing PC components market. Michael Hackworth was named president and chief executive officer in January 1985, and served as CEO until February 1999. It joined the Nasdaq market listing in 1989 (symbol: CRUS). Cirrus Logic acquired Crystal Semiconductor, a supplier of analog and mixed-signal converter ICs, in 1991. In the early 1990s, Cirrus Logic became a supplier of PC graphics chips, audio converters and chips for magnetic storage products. David D. French joined Cirrus Logic, Inc. as president and chief operating officer in June 1998 and was named chief executive officer in February 1999. Soon after joining the company, through an acquisition strategy French repositioned the company into a premier supplier of high-performance analog and digital processing chip solutions for consumer entertainment electronics, and soon afterwards, M. Yousuf Palla joined as Vice President of Operations and Manufacturing, contributing further to its success. The company announced in April 2000 that it had completed moving its headquarters to Austin, Texas. In June 2005, Cirrus Logic sold its video products operation to an investment firm, creating privately owned Magnum Semiconductor. After French resigned in March 2007, Jason Rhode, formerly the vice president and general manager of Cirrus Logic's Mixed Signal Audio Division, was named president and CEO in May 2007. In 2014 Cirrus Logic bought Wolfson Microelectronics for approximately $467 million. In 2021, Cirrus Logic acquired Lion Semiconductor for $335 million. It had a robotics partnership with the Ann Richards School, in which Cirrus Logic committed $10,000 a year for three years. In 2023 the robotics team was made up of 10 girls, which increased to 30 in 2024.
Following a change in focus, Cirrus Logic spun off its PC Modem business unit as Ambient Technologies in early 1999.
In early 2000, Intel purchased Ambient Technologies, subsequently renaming it their "Modem Silicon Operation" division.
In the early 1990s, Cirrus Logic was a supplier of low-cost PC graphics chips. Cirrus's Microsoft Windows 2D GUI accelerators (GDI) were among the fastest in the low-end market-segment, outperforming competing VGA chips from Oak Technologies, Trident Microsystems, and Paradise (Western Digital).[citation needed] For example, the Cirrus GD5422 (1992) supported hardware acceleration for both 8-bit color and 16-bit color. It was one of the lowest-priced SVGA controllers to support both.
