Silicon Laboratories designs chips and software for wireless connectivity in the Internet of Things. Its products are analogue-intensive, mixed-signal integrated circuits made in standard CMOS, combining functions that would otherwise need several discrete parts onto a single chip or system-on-chip. The range covers wireless microcontrollers and SoCs — including the EFM32, EFM8 and 8051 families — supporting Bluetooth, Wi-Fi, Zigbee, Z-Wave, Thread, Wi-SUN and sub-GHz radio, with the Simplicity Studio toolset.
The company is fabless, outsourcing wafer production to foundries, chiefly TSMC and SMIC, and earns revenue by selling to makers of connected devices. It reaches them through a direct sales force and a network of independent representatives and distributors, on individual purchase orders; two distributors, Arrow Electronics and Edom Technology, account for much of its sales.
Products address two markets, Industrial & Commercial and Home & Life, spanning applications from smart metering to door locks and glucose monitors. With sales offices in Asia, the Americas and Europe, 91% of fiscal 2025 revenue came from outside the United States. It employed 1,930 people in January 2026, 72% in engineering, and in February 2026 agreed to be acquired by Texas Instruments.
