Overview: SiWG917 SoC Single Chip Wi-Fi® and Bluetooth® LE Wireless Secure MCU Solutions Silicon Labs SiWG917 SoC is our lowest power Wi-Fi 6 plus Bluetooth LE 5.4 SoC, ideal for ultra-low power IoT wireless devices using Wi-Fi®, Bluetooth, Matter, and IP networking for secure cloud connectivity. It is optimal for developing battery operated devices that need long battery life. SiWG917 SoC includes an ultra-low power Wi-Fi 6 plus Bluetooth Low Energy (LE) 5.4 wireless CPU subsystem, and an integrated micro-controller (MCU) application subsystem, security, peripherals and power management subsystem all in a single 7x7 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®-M4 running up to 180 MHz, embedded SRAM, FLASH, ultra-low power sensor hub and AI/ML accelerator. The ARM® Cortex®M4 is dedicated for peripheral and application-related processing, while the ThreadArch® runs the wireless and networking stacks on independent threads, thus providing a fully integrated solution that is ready for a wide range of embedded wireless IoT applications.
