The SiWx917 SoC comprises an integrated microcontroller application subsystem (MCU), an enhanced security engine, peripherals, a power management subsystem, and a Wi-Fi 6 wireless CPU subsystem, as well as ultra-low-power Bluetooth Low Energy (LE) 5.4 that supports Matter over Wi-Fi and Wi-Fi 6 Target Wake Time (for extended battery life in long-term operating devices such as smart sensors and locks). The fully integrated, Matter-ready SiWx917 was designed to dramatically increase battery life and reduce power consumption in Wi-Fi IoT networks (up to 50% less power consumption than other competing Wi-Fi 6 and Bluetooth LE SoCs). It also delivers more computing power, faster AI/ML acceleration, and robust security to run all wireless stacks and multiple client applications—all on a single chip.
At the heart of the SiWx917's application subsystem is a 32-bit ARM® Cortex®-M4F running at up to 180 MHz, integrated SRAM, FLASH, an AI/ML accelerator, and a sensor hub dedicated to peripheral and application-related processing. The SoC is ideal for battery-powered devices in smart homes, consumer health and wearables, the medical, industrial, and retail sectors, smart buildings and cities, and asset tracking. The ultra-low-power SiWx917 SoC is compatible with the Si917-PK6031A Pro kit, which is also available from Mouser.
