Wi-Fi module adds Matter support

InnoPhase IoT, Inc. has expanded its Talaria TWO Wi-Fi platform, featuring STMicroelectronics’ STM32U5 ultra-low-power microcontroller (MCU), with Matter v1.2 support. The ultra-low-power Wi-Fi module targets smart home applications, including battery-operated sensors, doorbells, door locks, lighting, thermostats and other Matter devices.

A Matter over low-power Wi-Fi approach provides a direct connection to the cloud/internet without requiring a bridge border router, InnoPhase IoT said, simplifying the network topology and reducing costs.

The previously announced integration of STM32U5 and Talaria TWO enabled ultra-low-power sensor-to-cloud IoT solutions and by adding Matter v1.2 support, it enables smart-home devices with interoperability across multiple ecosystems, the company said.

The STM32U5 32-bit MCU integrates a Cortex-M33 core running at 160 MHz, with up to 4 MB of flash memory and 2.5 MB of SRAM. It reduces power by 90% thanks to proprietary features, thereby extending battery life.

“InnoPhase IoT’s Matter over Wi-Fi stack offloads both the Matter protocol processing and cloud connectivity onto the Talaria TWO SoC,” the company said. “This leaves greater compute power and memory on the MCU which developers can harness for applications.”

The software development kit (SDK) offers a scalable architecture, with a HAPI interface between Talaria TWO and STM32 MCUs for seamless integration. Reference applications, supporting Matter 1.2, Amazon AWS and Microsoft Azure platforms, are included.

Talaria TWO Wi-Fi/BLE modules are certified with the Wi-Fi Alliance and Bluetooth SIG and meet global regulatory certification. The Talaria TWO INP3014 Evaluation Kit, which integrates with STM32U5 series development boards, is currently available with Matter 1.2 support. The SDK 3.1, featuring reference Matter application profiles, is available for download at InnoPhase IoT and STMicroelectronics partner websites.
