Silicon Labs has launched a new generation of wireless chips aimed at powering connected devices in smart homes, buildings, and industrial settings, as competition intensifies in the Internet of Things (IoT) semiconductor market.
The Austin-based group, listed on Nasdaq, said its SiMG301 and SiBG301 system-on-chips (SoCs) are now shipping to customers and distributors globally. The devices are the first in its Series 3 platform, which the company said delivers improvements in computing power, integration, and energy efficiency over its existing Series 2 products.
The SiMG301 has also been certified under the Connectivity Standards Alliance’s (CSA) Matter Compliant Platform programme, which Silicon Labs said would allow device manufacturers to shorten development cycles and lower certification costs. Matter is an industry-backed protocol designed to ensure interoperability between smart home products.
Ross Sabolcik, Senior Vice President of IoT products at Silicon Labs, said the new chips combine higher performance with “the world’s first PSA Level 4 security”, providing a “stronger foundation for long-lived, secure IoT”.
PSA Level 4 certification — the highest recognised by the independent standard — requires chips to withstand advanced attacks including laser fault injection and micro-probing. The new SoCs are the first to achieve this level of certification, according to Silicon Labs, which said the feature would help customers comply with tightening regulations such as the EU’s Cyber Resilience Act and the US Cyber Trust Mark.
Built on a 22-nanometre process, the Series 3 architecture separates application, wireless, and security workloads across multiple cores, leaving headroom for more demanding use cases. The SiMG301 is designed for multiprotocol applications, including Zigbee, Bluetooth Low Energy, and Matter over Thread, while the SiBG301 targets Bluetooth-based designs. Both include integrated LED drivers for smart lighting and building applications.
Jon Harros, Global Head of Certification at the CSA, said Silicon Labs had played a “central role” in creating the new certification programme, and that including its devices among the first certified platforms “gives device makers a proven foundation to ship secure, feature-rich Matter products faster”.
Silicon Labs is positioning Series 3 as a complement to its widely adopted Series 2 chips, which remain optimised for ultra low power devices. The company said it expects device makers to adopt the new platform for more feature-rich designs without having to change ecosystems or development tools.
