Silicon Labs designs tiny, power-sipping chips that let everyday devices connect wirelessly and run on a battery for years.
Silicon Labs makes the small brains inside connected gadgets. Its chips are the part that handles radio signals, sensors, and power management, and they show up in smart home devices, fitness trackers, and medical monitors. If a product needs to talk wirelessly while sipping very little electricity, this is the kind of chip that makes it possible.
The company went all-in on this idea. It sold off its older infrastructure business, which made timing chips and other components for big telecom and data-center equipment, and now focuses almost entirely on the internet of things. That bet looks smart on paper, because the number of connected devices keeps climbing. But the market is crowded. Texas Instruments, NXP Semiconductors, and STMicroelectronics all sell competing chips, and many of them are bigger and cheaper. Silicon Labs tries to win by being easy to design with: it offers ready-made wireless blueprints and software so a small team can build a connected product without hiring a radio engineer. The business is cyclical, and that hurt badly. As interest rates rose and customers who had stockpiled chips during the shortage stopped ordering, sales tumbled. Revenue fell to roughly $590 million in 2024, down sharply from its pandemic peak. The company responded with cost cuts and layoffs, and it has been waiting for demand to recover.
The interesting part is who owns the company now. In 2025, Skyworks Solutions agreed to buy Silicon Labs in a cash-and-stock deal worth about $2.4 billion, a sign that the wireless chip industry is consolidating. Until that closes, Silicon Labs keeps shipping its low-power chips and betting that the connected-device wave is still early.
