We are happy to announce the latest family member of our electronic components supplier Silabs Wi-Fi 6 devices: SiWx915 SoC is ideal for energy efficient or line powered IoT wireless devices using Wi-Fi®, Bluetooth Low Energy (LE), Matter, and IP networking for cloud connectivity. It includes a Wi-Fi 6 plus Bluetooth LE wireless CPU subsystem, and an integrated micro-controller (MCU) application subsystem, Security, memory, peripherals subsystem all in a single 6x6 mm QFN package.
The wireless subsystem consists of a multi-threaded processor (ThreadArch®) running up to 160 MHz, baseband digital signal processing, analog front end, 2.4 GHz RF transceiver and integrated power amplifier. The application subsystem consists of an ARM® Cortex®-M4F running up to 180 MHz, embedded SRAM, and FLASH. The ARM® Cortex®-M4F is dedicated for peripheral and application related processing, while the ThreadArch® runs the wireless and networking stacks on independent threads, thus providing a high performance, fully integrated solution that is ready for a wide range of embedded wireless IoT applications: smart homes, consumer health and wearables, clinical medical, industrial, retail, smart building and cities, asset tracking.
