Silicon Labs provides solutions and software for use in a variety of electronic products in a range of applications including portable devices, AM/FM radios and other consumer electronics, networking equipment, test and measurement equipment, industrial monitoring and control, home automation and customer premises equipment. These products integrate complex mixed-signal functions that are frequently performed by numerous discrete components in competing products into a single chip or chipset.[12] Silicon Labs’ portfolio is organized around four primary businesses:

  • Internet of Things - which includes 8-bit and 32-bit microcontrollers (MCUs), environmental sensors such as relative humidity and temperature sensors, and human interface solutions such as capacitive touch controllers and proximity/ambient light sensors
  • Infrastructure - which includes timing ICs (clock generators and oscillators), digital isolators, wireless ICs (2.4 GHz ZigBee SoCs and sub-GHz transmitters, receivers and transceivers)
  • Broadcast - which includes single-chip AM/FM radios for consumer radio, automotive infotainment and professional audio applications and silicon TV tuners and demodulators for flat-screen TVs and set-top boxes
  • Access - which includes analog modems for set-top boxes, point of sale terminals and multi-function printers, SLICs for VoIP gateways, and PoE devices for networking gear

Silicon Labs groups products into several product families.

Product Family Description
