Advancing the IoT

Silicon Labs’ Wireless Gecko Series 2 platform is designed to make IoT products more powerful, efficient and reliable. The first wave of Series 2 devices are small form-factor SoCs with a dedicated security core and serve line-powered IoT applications including connected lighting, hubs and gateways, metering, and smart speakers.







Series 2 Enhanced Security

  • Dedicated Hardware Core
    • Faster, more energy efficient hardware encryption
    • A TRNG that is compliant with NIST SP 800-90A/B/C and AIS-31
    • Secure Debug control helps prevent unauthorized access to end products
  • Secure Boot
    • Ensures authentic firmware and OTA updates


Simplifying Wireless Designs with a Highly Integrated SoCs

  • Best-in-class RF with +20 dBm output power and up to +124.5 dB link budget
  • Powerful processing with an 80 MHz Arm® Cortex®-M33 core with TrustZone technology
  • Industry’s smallest multiprotocol SoCs in a 4 mm x 4 mm QFN package
  • Lower BOM count with fewer matching components and no need for external inductors or power amplifiers

One Kit to Rule Them All

Use the universal wireless starter kit and interchangeable radio boards with both EFR32MG21 Series 2 and EFR32BG21 Series 2.
