Silicon Labs has introduced the next generation of its Wireless Gecko platform, Series 2, designed to make Internet of Things (IoT) products more powerful, efficient and reliable. Building on the RF and multiprotocol capabilities of the Wireless Gecko portfolio, the initial Series 2 products include small-form-factor system-on-chip (SoC) devices with a dedicated security core and an on-chip radio delivering extended wireless range.
The first products in Silicon Labs’ Series 2 portfolio include EFR32MG21 SoCs supporting multiprotocol, Zigbee, Thread and Bluetooth mesh networking, and EFR32BG21 SoCs dedicated to Bluetooth Low Energy and Bluetooth mesh. These SoCs provide ideal solutions for line-powered IoT products including gateways, hubs, lights, voice assistants and smart electric meters.
Performance figures include: +20 dBm output power and up to +124,5 dB link budget; a robust wireless radio with improved blocking performance; powerful processing with an 80 MHz Arm Cortex-M33 core with TrustZone technology; and low active current (50,9 µA/MHz) to meet stringent green energy requirements.
The multiprotocol SoCs, which come in a 4 x 4 mm QFN package, provide enhanced security features that enable developers to implement robust security in connected products. A dedicated security core enables faster, lower-power encryption than software techniques, while a true random number generator (TRNG) strengthens device cryptography. Secure boot loading ensures authenticity of firmware images and over-the-air updates, and secure debug access control helps OEMs prevent unauthorised access to end-products.
Future pin- and software-compatible Wireless Gecko Series 2 SoCs and modules with additional dedicated security technologies will enable developers to create next-generation connected products with enhanced security features, helping to increase consumer trust and drive mass IoT adoption.
With Series 2, designers can bring secure, next-generation IoT products to market by taking advantage of Silicon Labs’ Simplicity Studio integrated development environment (IDE). The Simplicity Studio IDE accelerates time-to-market with a suite of tools, including a unified wireless development kit, SDKs, energy profiler, patented network analysis, application demos and mobile apps.
