Silicon Labs’ SiWx917Y series of Wi-Fi 6 and Bluetooth LE 5.4 modules provides plug-and-play simplicity with global RF certifications, helping to accelerate development. Intended for battery-powered IoT devices, these energy-efficient modules integrate an Arm Cortex-M4 application processor and antenna in a small 16×21×2.3-mm package.

The SiWG917Y variant enables customers to run all application code on the device’s Arm Cortex-M4 core. In contrast, the SiWN917Y allows customers to execute applications on a separate MCU, while the module manages Wi-Fi 6 and BLE 5.4 communication tasks. Intelligent power management supports connected sleep mode, consuming as little as 20 µA with Target Wake Time (TWT) and a 60-second keep-alive interval.
The wireless subsystem includes a 160-MHz network processor, baseband DSP, analog front-end, RF transceiver, and power amplifier. The application subsystem features a 180-MHz Cortex-M4 processor with a floating-point unit (FPU) for peripheral and application tasks. This dual-core architecture separates applications and wireless stacks to optimize performance and ensure timely processing.
Wireless modules in the SiWx917Y series are now generally available for purchase.
