Thread Products

OpenThread protocol implements all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support. It requires a small memory footprint and is highly portable. It is ideally suited for IPv6 based low power wireless device to device communication for home applications.

Our OpenThread portfolio:

Based on ST’s best-in-class, ultra-low-power STM32L4 microcontrollers, STM32WB dual-core wireless MCUs with OpenThread stack supports the IEEE 802.15.4 communication protocol in both single and concurrent mode, covering a wide spectrum of IoT application needs.

The STM32WB is a certified component for whatever Full Thread Device (FTD) or Minimal Thread Device (MTD) type of role is intended.

STM32WB series is a Thread certified component.

Thread Certified Component

Our wide choice of packages, including QFN, BGA, LGA86, Wafer Level Chip Scale Package (WLCSP) and pre-certified ready to use module, is complemented by a rich STM32Cube evaluation and development environment for speeding up time to market.

802.15.1 OpenThread SOC

STM32WB dual-core wireless MCU series and its certified OpenThread software stack give you access to an OpenThread solution for IP-based low-power wireless mesh networks which also supports BLE 5.2 concurrent mode.IEEE 802.15.4 is a technical standard – maintained by the IEEE 802.15 working group – that defines the physical layer and media access control (MAC) specifications for low-rate wireless personal area networks (LR-WPANs).

It thus provides a generic standard MAC layer that can be the basis for protocols – including ZigBee and Thread – which then define the upper layers of the stack. OpenThread in an open-source implementation of Thread® standard based on the broadly supported IEEE 802.15.4 radio standard.
