Insights

Semiconductor Analyst

Silicon Labs' general availability announcement of its MG26 SoC family represents a strategic advancement in the company's IoT connectivity portfolio and strengthens its competitive position in the rapidly expanding Matter ecosystem. This launch directly addresses the growing demand for interoperable, secure smart home devices with enhanced processing capabilities.

The MG26's concurrent multiprotocol support—enabling simultaneous Zigbee and Matter over Thread connectivity—solves a critical market challenge: allowing device manufacturers to create products that work across multiple ecosystems without requiring separate hardware SKUs. This feature provides Silicon Labs with a significant competitive advantage over single-protocol solutions from rivals like Texas Instruments and NXP in the fragmented smart home market.

From a technical perspective, the doubled memory capacity and dedicated AI/ML acceleration hardware position SLAB to capture higher-value segments of the IoT market. The embedded AI/ML accelerator delivers 8x faster processing using 1/6th the power compared to CPU-only solutions—enabling advanced edge computing applications that weren't previously feasible in battery-powered devices.

The company's Custom Part Manufacturing Service offering pre-programmed Matter device attestation certificates addresses a critical pain point in the IoT security landscape, potentially accelerating customer time-to-market while creating a sticky platform relationship that could increase switching costs.

Nuki's adoption of the technology for their US market entry validates the platform's value proposition, particularly for battery-sensitive applications requiring robust security and multi-protocol support. As the Matter ecosystem expands beyond its initial device categories, Silicon Labs' position as the leading semiconductor code contributor to the standard should translate to earlier access to emerging opportunities.

This product launch aligns with Silicon Labs' strategic focus on wireless connectivity following its divestiture of non-core businesses, potentially strengthening margins as the company targets higher-value IoT applications requiring advanced security and AI/ML capabilities at the edge.

MG26 SoCs are now generally available, providing developers with the highest performance and AI/ML capabilities

AUSTIN, Texas, Feb. 26, 2025 /PRNewswire/ -- Silicon Labs (NASDAQ: SLAB), a leader in secure, intelligent wireless technology for a more connected world, today announced that its MG26 family of wireless SoCs is now generally available through Silicon Labs and its distribution partners. As the industry's most advanced, high-performance Matter and concurrent multiprotocol solution to date, the MG26 SoC features double the Flash and RAM of other Silicon Labs multiprotocol devices, advanced AI/ML processing, and best-in-class security to empower developers to design future-proof Matter applications.

"With MG26, we're not just setting a new standard in multiprotocol wireless performance for battery-based, low-power smart home applications—we're redefining what's possible for the future of IoT connectivity with Matter," said Jacob Alamat, Senior Vice President for the Home and Life business unit at Silicon Labs. "This device empowers developers to create smarter, safer, and more powerful solutions in an increasingly connected world."

Further enhancing security through its Custom Part Manufacturing Service (CPMS), Silicon Labs is the only Matter SoC device maker that allows customers to customize their order with their own Matter device attestation certificates (DAC), simplifying and accelerating product launches using Silicon Labs Matter-enabled SoCs while preventing IP theft and counterfeiting.

MG26 SoC Powers Advanced IoT Applications and Matter

The MG26 SoC significantly advances Matter adoption with its concurrent multiprotocol capabilities, enabling integration of various Smart Home and Building devices like LED lighting, switches, sensors, and locks into both Matter and Zigbee networks simultaneously. This allows users to create automations and routines that incorporate more devices across different ecosystem.  

In addition, the MG26's AI/ML capabilities using its embedded accelerator also enhance its performance in critical tasks like predictive maintenance, anomaly detection, keyword detection, vision, and more and more applications that span across the IoT. To help developers build devices capable of running advanced IoT applications, the MG26 family offers:

• Higher compute in a multicore format with an ARM^® Cortex^®-M33 CPU and dedicated cores for the radio and security subsystems, freeing up the main core for customer applications.
• Doubled Flash, RAM, and GPIO capacity compared to the MG24 device family, allowing IoT device builders to develop advanced edge applications that leverage larger, more accurate machine learning models for improved performance. It also allows for the processing of larger machine learning workloads like higher resolution vision.
• Embedded AI/ML hardware acceleration, enabling up to 8x faster processing of machine learning algorithms using as little as 1/6th the power compared to running on the CPU. Silicon Labs' new AI/ML Developer Journey provides an easy on-ramp for developers to start building new models to take advantage of this processing power.
• Best-in-class security with Silicon Labs Secure Vault™ and ARM TrustZone, compliant with all Matter security requirements.
  • Using Silicon Labs Custom Part Manufacturing Service, MG26 devices can also be programmed with customer Matter device attestation certificate (DAC), security keys and other features in the fabrication process on demand, further hardening them against vulnerabilities.
  • Secure OTA firmware updates in conjunction with Secure Boot prevent the installation of malicious software and allow for vulnerability patching.
• Concurrent Multiprotocol, enabling the ability to run both Zigbee and Matter over Thread at the same time, simplifying SKU management for the product manufacturer and ease of use for the end user.
• Industry-leading RF performance to energy-efficiency ratio, with transmission power of up to +19.5 dBm and world-leading receiver sensitivity with ultra-low TX, RX, and sleep currents enable long-life battery-powered IoT devices with superior wireless performance.
