Wireless SoCs from Texas-based Silicon Labs can help developers design future-proof Matter applications.

The MG26 family has been made generally available through Silicon Labs and its distributors. The SoCs have double the flash and RAM of other Silicon Labs multiprotocol devices, combined with AI and ML processing, and security.

“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 at Silicon Labs.

Enhancing security through its CPMS custom part manufacturing service, Silicon Labs says it is the only Matter SoC device maker that allows customers to customise their order with their own Matter device attestation certificates (DACs), simplifying and accelerating product launches while preventing IP theft and counterfeiting.

The SoC advances Matter adoption with its concurrent multiprotocol capabilities, enabling integration of various smart home and building devices such as LED lighting, switches, sensors and locks into Matter and Zigbee networks simultaneously. This allows users to create automations and routines that incorporate more devices across different ecosystem.

In addition, the AI and ML capabilities using its embedded accelerator also enhance its performance in critical tasks such as predictive maintenance, anomaly detection, keyword detection and vision, and more applications that span across the IoT.

To help developers build devices capable of running IoT applications, the family offers 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 user applications.

Doubled flash, RAM and GPIO capacity compared with the MG24 device helps IoT device builders develop edge applications that leverage larger, more accurate machine-learning models for improved performance. It also allows for the processing of larger machine-learning workloads such as higher resolution vision.

Embedded AI and ML hardware acceleration enables up to eight-times faster processing of machine-learning algorithms using a sixth of the power compared with running on the CPU.

Silicon Labs’ AI and ML Developer Journey provides an easy on-ramp for developers to start building models to take advantage of this processing power.

The firm’s Secure Vault and Arm TrustZone are compliant with all Matter security requirements.

Using CPMS (www.silabs.com/services/custom-part-manufacturing-service), the devices can also be programmed with customer Matter DACs, security keys and other features in the fabrication process on demand, hardening them against vulnerabilities. Secure OTA firmware updates with secure boot prevent the installation of malicious software and allow for vulnerability patching.

Concurrent multiprotocol enables the ability to run Zigbee and Matter over Thread at the same time, simplifying SKU management for the product manufacturer and ease of use for the end user.

The RF performance to energy-efficiency ratio, with transmission power of up to +19.5dBm and receiver sensitivity with low TX, RX and sleep currents, enables long-life battery-powered IoT devices with better wireless performance. 

Austrian smart lock manufacturer Nuki (nuki.io), which will enter the US market this year, chose Silicon Labs (www.silabs.com) as Matter partner for its latest smart lock to achieve reliable, efficient connectivity. It is Nuki’s first electronic lock that’s not only compatible with European doors but also with US deadbolts. Silicon Labs Matter-ready SoCs enable Nuki’s smart locks to operate for extended periods without frequent battery replacements, support various wireless protocols using Matter, and ensure seamless connectivity to home networks.

“Silicon Labs’s Matter-ready SoCs enable us to bring super compact, battery-driven devices with parallel support for several communication protocols to the market,” said Jürgen Pansy, co-founder of Nuki. “Our latest innovation, the award-winning smart lock, supports Matter via Thread using Silicon Labs hardware that saves energy and space in the lock’s design to allow for additional connectivity integrations like Bluetooth LE and wifi.”
