that need long battery life. SiWG917 SoC includes an ultra-low power Wi-Fi 6 plus Blue-
tooth 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-threa-
ded processor (ThreadArch®) running up to 160 MHz, baseband digital signal process-
ing, analog front end, 2.4 GHz RF transceiver and integrated power amplifier. The appli-
cation 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 Threa-
dArch® 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 appli-
cations.
