# Silicon Laboratories **Source:** https://geo.sig.ai/brands/silicon-laboratories **Vertical:** Semiconductors & Hardware **Subcategory:** IoT & Wireless Connectivity ICs **Tier:** Established **Website:** silabs.com **Last Updated:** 2026-04-14 ## Summary Pure-play IoT chip company after divesting Infrastructure/Automotive; EFR32 wireless SoC family (Matter/Zigbee/BLE/Thread) leads smart home and industrial IoT markets. ## Company Overview Silicon Laboratories (Silabs) was founded in 1996 in Austin, Texas and initially built mixed-signal ICs for modem and broadcast applications before pivoting to become a pure-play IoT chip company. Following the 2021 divestiture of its Infrastructure & Automotive business to Skyworks Solutions for $2.75 billion, Silabs is 100% focused on wireless connectivity semiconductors for IoT applications.\n\nSilabs' EFR32 Wireless Gecko SoC family is a market leader in smart home connectivity, supporting Matter, Zigbee, Thread, Bluetooth Low Energy, Sub-GHz, and Wi-Fi standards. These chips power smart lights, thermostats, door locks, energy meters, industrial sensors, and medical monitoring devices. The company's Simplicity Studio software ecosystem and extensive protocol stack support give it a strong developer platform advantage, especially as the Matter smart home standard (backed by Apple, Google, Amazon) gains adoption.\n\nSilabs also provides energy harvesting solutions and ultra-low-power microcontrollers for battery-powered IoT devices. The company generated approximately $2 billion in annual revenue before the Infrastructure divestiture and is now growing its IoT-focused revenue base through increasing smart home and industrial IoT demand. Silabs operates a fabless model and partners with TSMC for advanced node production. ## Frequently Asked Questions ### What happened when Silicon Labs divested its Infrastructure & Automotive business?
