The wireless chips make smart devices faster and use less power. They work with multiple systems and fit into homes, cities, healthcare, and more.
Silicon Labs has announced the first products in its Series 3 portfolio with the launch of two new wireless SoC families: the SiXG301 and SiXG302. Built on a 22-nanometer (nm) process, these solutions represent a step forward in processing power, integration, security, and energy use—meeting the needs of both battery-powered and line-powered IoT devices.
As smart devices become smaller and more capable, the need for secure and integrated wireless solutions is increasing. The new Series 3 SoCs provide processing capabilities, memory options, security features, and support for integration with external components. Silicon Labs’ Series 1, Series 2, and Series 3 platforms will continue to support a range of IoT applications.
Designed for line-powered devices, the SiXG301 includes an integrated LED pre-driver and supports Bluetooth, Zigbee, and Thread with Matter. With 4 MB of Flash and 512 kB of RAM, it meets growing requirements for Matter and other IoT applications. The SoC supports simultaneous operation of Zigbee, Bluetooth, and Matter over Thread, which helps reduce manufacturing SKUs, lower costs, free board space, and simplify user experience.
Extending the Series 3 line to battery-powered devices, the SiXG302 provides energy use efficiency while maintaining function. It uses 15 µA/MHz of active current, 30% less than other devices in the same category, using Silicon Labs’ power architecture. The SiXG302 supports wireless sensors and actuators for Matter and Bluetooth.
By using the 22 nm process node across all Series 3 devices, the company claims to address the need for more capable and efficient far-edge devices across various IoT use cases, including cities, industrial systems, healthcare, and homes. These SoCs provide a platform for creating secure, scalable IoT products.
“Smart devices are becoming more complex, and designers are challenged to pack greater functionality into smaller spaces while maintaining energy efficiency,” said Ross Sabolcik, Senior Vice President of Product Lines at Silicon Labs. “With the SiXG301 and upcoming SiXG302 families, we’re delivering flexible, highly integrated solutions that enable next-generation IoT devices—whether they’re plugged in or running on battery power.”
