STMicroelectronics ST67W611M1 IoT module

STMicroelectronics has introduced the first product in its strategic collaboration with Qualcomm Technologies to simplify development of next-generation wireless solutions for industrial and consumer IoT applications. The collaboration will deliver IoT modules leveraging ST’s powerful STM32 ecosystem and Qualcomm’s wireless connectivity solutions.

The first of these modules, the ST67W611M1, contains a Qualcomm QCC743 multiprotocol connectivity system-on-a-chip (SoC) pre-loaded with Wi-Fi 6, Bluetooth 5.3 qualified and Thread combo, making it easy to integrate with any STM32 microcontroller (MCU) or microprocessor (MPU). The module will support Matter protocol over Wi-Fi for futureproof connectivity, making the STM32 portfolio seamlessly accessible to the Matter ecosystem. Aiding the system integration, the module also contains 4 MB Flash for code and data storage, and a 40 MHz crystal. There is also an integrated PCB antenna or micro RF (uFL) connector for an external antenna.

Advanced hardware security is built in, with hardware cryptographic accelerators as well as services including secure boot and secure debug, reaching PSA Certified Level 1 protection. The module is self-contained and pre-certified according to mandatory specifications, requiring no RF design expertise from the user to create a working solution. Highly integrated in a 32-lead LGA package, it is ready to place on the board and permits simple, low-cost PCB designs with as few as two layers.

The module leverages the STM32 ecosystem, which contains over 4000 commercial part numbers, powerful STM32Cube tools and software, and enhancements that boost edge AI development. AI enhancements include the recently introduced STM32N6 MCUs, which contain ST’s Neural-ART Accelerator, and the ST Edge AI Suite that provides an AI Model Zoo and STM32Cube.AI and NanoEdge AI optimisation tools.

The modules are designed to be quickly and seamlessly integrated with any STM32 MCU or STM32 MPU, offering flexible options for performance, price and power across a broad spectrum. The MCUs available range from cost- and power-sensitive devices containing the Arm Cortex-M0+ core to devices containing high performing cores such as Cortex-M4 and Cortex-A7 in the STM32MP1/2 MPUs.
