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
