Products[edit]

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.

Silicon Labs’ portfolio is organized around three primary businesses:

  • Broad-based - which includes 8-bit and 32-bit microcontrollers (MCUs), timing ICs (clock generators and oscillators), digital isolators, wireless ICs (2.4 GHz ZigBee SoCs and sub-GHz transmitters, receivers and transceivers), environmental sensors such as relative humidity and temperature sensors, and human interface solutions such as capacitive touch controllers and proximity/ambient light sensors
  • 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
MCUs Microcontrollers include 8-bit MCUs and 32-bit wireless MCUs based on the ARM architecture Cortex-M0/M3/M4 cores. This product family also includes peripheral devices such as EZRadio transceivers.
Wireless Silicon Labs offers wireless and RF IC solutions. Products include ISM band receiver ICs, wireless MCUs, FM and multi-band radio ICs, Ember ZigBee and Thread 802.15.4 wireless networking solutions, and Wireless M-Bus.
