Silicon Laboratories Inc.
Could not find a ticker for this position, may be a filing error
A fabless semiconductor company that designs chips for the Internet of Things, Silicon Labs makes low-power microcontrollers and wireless system-on-chips (like the EFR32 series) that let smart-home devices, industrial gear, and wearables talk over Bluetooth, Zigbee, and Wi-Fi. Founded in Austin, Texas in 1996 by three engineers who flipped a coin to decide whether to start the company, it first made its mark with a silicon replacement for the bulky transformers every telephone modem once required.
