Silicon Laboratories, Inc., commonly referred to as Silicon Labs, is a fabless global technology company that designs and manufactures semiconductors, other silicon devices and software, which it sells to electronics design engineers and manufacturers in Internet of Things (IoT) infrastructure worldwide.

Contents

It is headquartered in Austin, Texas, United States. The company focuses on microcontrollers (MCUs) and wireless system on chips (SoCs) and modules. The company also produces software stacks including firmware 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 updated DAA design that enabled manufacturers to reduce the size and cost of a modem. [4] During its first three years, the company focused on RF and CMOS integration, [4] and developed the world's first CMOS RF synthesizer 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. Silicon Labs direct access arrangement (DAA) IC.png
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]

Company history

Silicon Labs was founded by Crystal Semiconductor (now owned by Cirrus 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 updated DAA 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 improved RF 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 to Skyworks 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]
