Silicon Labs, a leader in low-power wireless connectivity technology, has introduced a new family of wireless SoCs, the SiXG301 and SiXG302, manufactured on a 22nm process node.

This product is the first in Silicon Labs’ Series 3 platform lineup, which delivers dramatic improvements in computing performance, energy efficiency, security and integration capabilities.

As smart devices become smaller and more complex, the need for robust and reliable wireless solutions is increasing. Silicon Labs’ Series 3 SoCs feature flexible memory options, best-in-class security and external component simplification to address a wide range of IoT applications.

It is planned to complement and respond to IoT-wide applications together with the previous generation Series 1 and Series 2 platforms.

The SiXG301 integrates an LED pre-driver and supports Thread protocols for Bluetooth, Zigbee, and Matter.

In particular, it is designed to be ideal for advanced smart home devices and LED lighting solutions based on Matter.

It features 4MB flash and 512kB RAM, providing expandability for future-oriented designs.

Simultaneous execution of Zigbee, Bluetooth, and Matter over Thread simplifies SKU manufacturing, reduces costs, and improves consumer convenience.

Mass production is expected to begin in the third quarter of 2025.

The SiXG302 supports high-efficiency battery operation and incorporates groundbreaking power-saving technology.

The ultra-low power design of 15μA/MHz reduces power consumption by 30% compared to existing competitive products, and is optimized for Matter and Bluetooth wireless sensors and actuators. Samples are expected to be available in 2026.

With this SoC, Silicon Labs aims to support a wide range of IoT applications, including smart cities, industrial automation, healthcare, and smart homes.

“As smart devices become more complex, designers are demanding higher performance and energy efficiency in smaller spaces,” said Ross Sabolcik, senior vice president of products. “The SiXG301 and SiXG302 families provide flexible solutions optimized for battery- and wired-powered IoT devices.”
