Wireless platform enables connected products to scale the IoT

IoT developers routinely face product design tradeoffs around wireless range, power consumption, size, security and cost.

The Series 2 wireless connectivity portfolio simplifies IoT product design with highly integrated SoC options and reusable software that make RF communication more dependable and energy efficient. Series 2 helps developers optimise system cost and performance for a wide range of smart home, commercial and industrial IoT applications.

“As the adoption and diversity of IoT devices continue to grow, developers seek flexible connectivity solutions that help them quickly bring differentiated products to market while reducing cost and design complexity,” said Matt Johnson, Senior Vice President and General Manager of IoT products at Silicon Labs.

“Series 2 improves multiple design elements, including wireless performance, software reuse, RF communication reliability and enhanced security to speed development, deployment and adoption of the IoT.”

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 suitable solutions for line-powered IoT products including gateways, hubs, lights, voice assistants and smart electric meters.

Series 2 SoCs provide developers with unmatched system design advantages:

• RF performance with +20dBm output power and up to +124.5dB link budget
• Robust wireless radio with improved blocking performance
• Powerful processing with an 80MHz Arm Cortex-M33 core with TrustZone technology
• Low active current (50.9µA/MHz) to meet stringent green energy requirements, a benefit of manufacturing on low power 40nm process technology
• Multiprotocol SoCs in a 4x4 mm QFN package
• Lower BOM count and system cost with fewer matching components and no need for external inductors or power amplifiers
• Flexible pre-certified modules based on EFR32xG21 SoCs planned for Q3

Secure by Design
EFR32xG21 SoCs 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.
• A True Random Number Generator (TRNG) strengthens device cryptography.
• Secure boot loading ensures authenticity of firmware images and over-the-air updates.
• 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-gen connected products with enhanced security features, helping to increase consumer trust and drive mass IoT adoption.

With Series 2, designers can bring secure, next-gen IoT products to market by taking advantage of Silicon Labs’ Simplicity Studio market with a suite of tools, including a unified wireless development kit, SDKs, energy profiler, patented network analysis, application demos and mobile apps.
