Silicon Labs Sets New Standards in IoT with Series 3 SoCs

Silicon Labs, a renowned leader in low-power wireless technology, has officially announced the debut of its Series 3 portfolio, featuring the groundbreaking SiXG301 and SiXG302 wireless System-on-Chip (SoC) families. Built at the cutting-edge 22 nanometer (nm) process node, these new SoCs represent a substantial advancement in computing power, energy efficiency, security, and integration for Internet of Things (IoT) devices.

Addressing Growing IoT Demands

In today's rapidly evolving technological landscape, smart devices are increasingly sophisticated, compact, and powerful. This growth drives the need for robust, secure, and highly integrated wireless solutions. Silicon Labs' Series 3 SoCs meet this demand with advanced processing capabilities, flexible memory configurations, and some of the best security features in the market.

SiXG301: Tailored for Line-Powered Devices

The SiXG301 is purpose-built for line-powered smart applications. It comes with an integrated LED pre-driver, making it a prime choice for advanced LED smart lighting and various smart home products. Supporting multiple protocols, including Bluetooth, Zigbee, and Thread, the SiXG301 is designed with both 4 MB of Flash memory and 512 kB of RAM. This combination allows it to handle even the most demanding applications efficiently. With its ability to operate multiple protocols simultaneously, the SiXG301 simplifies the manufacturing process, reduces costs, and conserves board space, enhancing user experience. Currently, it is in production with selected customers and is expected to be widely available by Q3 2025.

SiXG302: A Leap in Energy Efficiency

On the flip side, the SiXG302 targets battery-powered devices. Its design boasts groundbreaking energy efficiency, operating at just 15 µA/MHz of active current—30% lower than rivals. This makes it perfect for battery-powered sensors and actuators, reinforcing its compatibility with both Matter and Bluetooth applications. The SiXG302 is anticipated to be available for customer sampling in 2026, setting the stage for a new level of performance in battery-operated IoT devices.

Meeting Design Challenges

As smart device designers face the challenge of integrating greater functionality into smaller formats while maintaining energy efficiency, Silicon Labs is stepping forward with versatile solutions. Ross Sabolcik, the Senior Vice President of Product Lines at Silicon Labs, emphasized the need for such products: "Smart devices are becoming more complex, and designers are challenged to pack greater functionality into smaller spaces while maintaining energy efficiency." The SiXG301 and upcoming SiXG302 families exemplify the company's commitment to deliver flexible, integrated solutions that enable the development of the next-gen IoT devices.

Comprehensive IoT Application Coverage

Silicon Labs' Series 3 platform is designed for scalability and security, thereby addressing the increasing demand for advanced far-edge devices across various applications, from smart homes and cities to industrial automation and healthcare. The introduction of the SiXG301 and SiXG302 families not only expands the capabilities of the existing Series 1 and Series 2 platforms but also affirms Silicon Labs' position as a trusted partner in the development of innovative IoT products.

Upcoming Events and Additional Information

In addition to their product launch, Silicon Labs is gearing up to showcase the SiXG301 at the upcoming Works With 2025 conference series, an international event that gathers industry experts to discuss the latest technological trends and best practices. The series will take place in multiple locations, including Austin, TX and Bangalore, and will also feature a virtual edition for broader accessibility.
