Silicon Labs Series 3 SoCs Now Available to Power the Next Era of Connectivity

Silicon Labs announced at its Works With Summit event in Austin, TX, the general availability of the first products in its new Series 3 platform: the SiMG301 and SiBG301 SoCs. The devices, the first in the SixG301 family, are now shipping from Silicon Labs and authorized distribution partners worldwide. Series 3 extends Silicon Labs' leadership at the intelligent edge, delivering generational gains in compute, connectivity, integration, and security while complementing the company's proven Series 2 platform.

Device makers can continue to build on Series 2's breadth and maturity for ultra-low-power endpoints, and adopt Series 3 for more demanding, and designs--without changing ecosystems, tools, or support models. Built on an advanced 22 nm process, Series 3 introduces a multi-core architecture that separates application, wireless, and security workloads, providing headroom for growing protocol stacks and emerging compute-intensive use cases at the edge. The SixG301 family consists of: SiMG301 (Multiprotocol): Concurrent Zigbee®?, Bluetooth®?

LE, and Matter over Thread; ideal for smart lighting, and other Matter-focused switches, sensors, and controllers. An integrated LED pre-driver reduces external components, BOM cost, and board space in line-powered designs. SiBG301 (Blu Bluetooth-Optimized): Tailored for Bluetooth LE applications that benefit from Series 3 compute and security, with an easy migration path from Series 2 Bluetooth designs.

Both devices offer developers generous Flash/RAM headroom with up to 4 MB Flash and 512 kB RAM. They both include Silicon Labs' PIXELRZ single wire communication interface for LED controller ICs as well as a LED pre-driver that enables low level and consistent dimming, which together simplify designs, reduce costs, and provide efficient power for smart home lighting, smart building lighting, and other lighting applications. The SiMG301 is among the first devices included in the Connectivity Standards Alliance's new Matter Compliant Platform Certification program.

A Matter Compliant Platform is a tested combination of SDK and designated hardware that has been certified by the Alliance for core Matter functionality. By building on a certified platform, device makers can inherit pre-tested commissioning, networking, and message security, significantly reducing the number of tests required for end-product certification. Teams can also take advantage of the Alliance's Fast Track and Rapid Recertification programs when the underlying platform remains unchanged, shortening development cycles and lowering costs.

Products built this way are referred to as Derived Matter Products (DMPs). Series 3 Secure Vault, debuting with the SixG301 family, has achieved the world's first PSA Level 4 certification, the highest level recognized by PSA Certified and addresses advanced physical attacks. This certification validates Silicon Labs SoCs equipped with Series 3 Secure Vault, like the SiMG301 and SiMG301, for resilience against laser fault injection, side-channel analysi s, micro-probing, and voltage manipulation.

This raises the bar for edge protection and supports alignment with tightening global regulations. The certification followed independent lab evaluation. Built on Silicon Labs' Series 2 security legacy, Series 3 Secure Vault includes a hardened root of trust, lifecycle controls, and secure OTA update support for products expected to live in the field for years.
