Introduction

On October 2, 2025, at the Works With Summit in Austin, Texas, Silicon Labs (NASDAQ: SLAB), a pioneering leader in low-power wireless technology, introduced its Series 3 platform, featuring the SiMG301 and SiBG301 system-on-chips (SoCs). These innovative devices represent a significant advancement in the realm of Internet of Things (IoT) solutions, designed to meet the demands of compute-intensive applications with enhanced connectivity and robust security features.

Key Features of Series 3 SoCs

The Series 3 SoCs are built on a cutting-edge 22 nm process, integrating a multi-core architecture that separates application, wireless, and security tasks. This design not only provides scalability for growing protocol stacks but also supports emerging use cases that require significant computational power at the edge. The SixG301 family includes:

• - SiMG301 (Multiprotocol): Configured for concurrent usage of Zigbee®, Bluetooth® LE, and Matter over Thread, making it ideal for smart lighting and other Matter-centric devices. It features an integrated LED pre-driver that minimizes external components and cuts down on costs.
• - SiBG301 (Bluetooth-Optimized): Specifically crafted for Bluetooth LE applications, it offers an easy transition from earlier Series 2 Bluetooth designs while leveraging the enhanced compute and security capabilities of Series 3.

Both SoCs boast impressive specifications, including up to 4 MB flash memory and 512 kB RAM, along with Silicon Labs' PIXELRZ communication interface for LED controllers, vastly simplifying design requirements and reducing costs for smart home and building lighting systems.

Enhanced Market Readiness with Matter Compliance

The SiMG301 SoC is among the first devices to achieve certification in the Connectivity Standards Alliance's new Matter Compliant Platform Certification program. This certification guarantees core functionalities that streamline the product development process and ease the path toward end-product certification. By utilizing a certified platform, developers gain access to pre-tested commissioning and security features, which expedites the product launch cycle and lowers overall testing burdens.

Silicon Labs has long been a key contributor to the Matter initiative, showcasing leadership and commitment to creating interoperable products that adhere to the latest industry standards. With the introduction of the Matter Compliant Platform Certification program, device makers can ship secure, feature-rich products more swiftly, meeting the market's growing demand for innovative IoT solutions.

Unmatched Security with PSA Level 4 Certification

Security remains a foundational aspect of the Series 3 architecture, highlighted by its recognition as the world's first to achieve PSA Level 4 certification, the highest standard set by the PSA Certified initiative. This level of security addresses sophisticated physical attacks, including protection against laser fault injection and voltage manipulation. The Series 3 Secure Vault is built on a hardened root of trust, integrated lifecycle controls, and supports secure over-the-air (OTA) updates, positioning Silicon Labs at the forefront of edge device protection in an increasingly regulated environment.

Jon Harros, Global Head of Certification at the Connectivity Standards Alliance, emphasized the key role Silicon Labs plays in ensuring robust Matter implementations and highlighted the potential of the SiMG301 device to provide a proven foundation for expedited secure product launches.

Availability and Developer Resources

The SiMG301 and SiBG301 are now shipping globally and are available through Silicon Labs and authorized distributors. Developers looking to innovate in the IoT space can take advantage of evaluation kits, reference applications, and a guided Matter Developer Journey that includes certification checklists and lab-ready testing projects. Resources are available to accelerate product development cycles, ensuring a smooth transition into the expanding IoT market landscape.

Conclusion

In conclusion, Silicon Labs' Series 3 platform, featuring the SiMG301 and SiBG301 SoCs, marks a significant leap forward in low-power wireless technology for IoT. By combining advanced compute capabilities, enhanced security measures, and compliant solutions with the Matter standard, Silicon Labs positions itself as a leading partner for developers aiming to create the next generation of secure and connected IoT devices.
