IoT-Optimized Wi-Fi

Our SiWx917M SoC is our lowest power Wi-Fi 6 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. SiWx917M SoC includes an ultra-low power Wi-Fi 6 and 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 Network Wireless Processor 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, FLASH, and Sensor Hub. The ARM® Cortex®-M4F is dedicated for peripheral and application-related processing, while the network wireless processor 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.

Target applications include Smart Homes, Consumer Health and Wearables, Medical, Industrial, Retail, Smart Building and Cities, Asset Tracking.

Our SiWx917Y Wireless Module provides ultra-low-power Wi-Fi 6 and Bluetooth Low Energy LE 5.4 multiprotocol 2.4 GHz connectivity for energy-sensitive and battery-powered IoT devices. With the integrated antenna and worldwide RF regulatory certifications, the SiWx917Y Wireless Module reduces the time and costs needed for development and certifications. The ARM® Cortex®-M4 application microcontroller subsystem, Matter-support, large memory, Sensor Hub, and a rich set of peripherals make the SiWx917Y Wireless Module a versatile solution for any IoT use case. The intelligent power management delivers high-performance, long-range Wi-Fi 6 connectivity at the lowest power in its class, maximizing battery life and minimizing energy consumption for smart IoT devices.

Our SiWx917Y Module packs a fully integrated, shielded IoT wireless computing solution with an antenna, and worldwide RF-certifications in a package with dimensions of 16 x 21 x 2.3 mm. There are multiple orderable part numbers (OPN) available with different antenna, PSRAM, and Flash configurations and three operational modes: hostless system-on-chip (SoC), network co-processor (NCP), and radio co-processor (RCP), offering an optimal solution for IoT applications such as Smart Homes, Smart Cameras, Appliances, Consumer Health and Wearables, Clinical Medical, Industrial, Smart Building, and Asset Tracking.

The wireless subsystem consists of a network wireless processor running up to 160 MHz, baseband digital signal processing, analog front-end, RF transceiver, and integrated power amplifier. The application subsystem consists of an ARM® Cortex® M4 Processor with FPU subsystem running up to 180 MHz dedicated to peripheral and application processing. The high-performance dual-core architecture runs the applications and wireless stacks on separate cores to maximize performance and throughput and to guarantee timely processing of time-sensitive applications.

The SiWx917Y modules support RF regulatory certifications worldwide. They have modular radio type approvals for countries such as the USA (FCC), Canada (IC/ISED), MIC (Japan), and more. They also comply with the relevant EN standards (including EN 300 328 v2.2.2) for conformity with the directives and regulations in the EU (CE) and UK (UKCA) (Contact Silicon Labs sales for more details).
