Silicon Laboratories, Inc., commonly referred to asSilicon Labs, is afabless global technology company that designs and manufacturessemiconductors, other silicon devices andsoftware, which it sells to electronics design engineers andmanufacturers inInternet of Things (IoT) infrastructure worldwide.
It is headquartered inAustin, Texas, United States. The company focuses onmicrocontrollers (MCUs) and wirelesssystem on chips (SoCs) and modules. The company also producessoftware stacks includingfirmware libraries and protocol-based software, and a free software development platform called Simplicity Studio.[3]
Silicon Labs was founded in 1996 and two years later released its first product, an updatedDAA design that enabled manufacturers to reduce the size and cost of a modem.[4] During its first three years, the company focused onRF andCMOS integration,[4] and developed the world's first CMOS RFsynthesizer for mobile phones which was released in 1999.[4] Following the appointment of Tyson Tuttle as the CEO in 2012,[5] Silicon Labs has increasingly focused on developing technologies for the IoT market,[6] which in 2019 accounted for more than 50 percent of the company's revenue,[7] but in 2020 had increased to about 58 percent.[8]
In 1998, Silicon Labs released its first product, an updated Direct Access Arrangement (DAA) design that enabled manufacturers to reduce the size and cost of a modem.
In August 2019, Silicon Labs had more than 1,770 patents worldwide issued or pending.[9]
Silicon Labs was founded byCrystal Semiconductor (now owned byCirrus Logic Inc.) alumni Nav Sooch, Dave Welland and Jeff Scott in 1996.[10] It became a publicly traded company in 2000.[10] The first product, an updatedDAA design, was released in the market in 1998. It cost significantly less than traditional DAAs and used less space compared to established products, which made it an instant success, taking the company's sales from $5.6 million in 1998 to nearly $47 million in 1999.[4]
During its early years, the company focused on developing an improvedRF synthesizer for mobile phones that would cost less and take up less space. It introduced its first RF Chip in late 1999.[4]
Since 2012, Silicon Labs has been increasingly focused on developing technologies for the evolving IoT market.[6] On April 22, 2021, Silicon Labs announced the sale of its infrastructure and automotive business toSkyworks Solutions Inc for $2.75 billion.[11] The deal was closed on July 26, 2021.[12]
In July 2021, it was announced that Tyson Tuttle would be stepping down as CEO.[13] In January 2022 former president, Matt Johnson, completed the transition into the CEO position.[14]
In 2015, launchedThread networking technology for connecting devices including wireless sensor networks, thermostats, connected lighting devices and control panels.[28]
In 2016, released Gecko family of multiprotocol wirelessSoC devices.[29]
In 2017, launched industry's first wireless clocks that support4G/LTE andEthernet.[30]
In 2018, launchedZ-Wave 700 hardware/software IoT platform.[31]
In 2019, launched updated version of wireless Gecko web development platform.[32]
