It is optimal for developing battery operated devices that need long battery life. SiWG917 module 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 16 x 21.1 x 2.3 mm package. The wireless subsystem consists of a multi-threaded Network Wireless Processor (NWP) 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 matrix vector processor. The ARM® Cortex®-M4 is dedicated for peripheral and application-related processing, while the NWP 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. The modules come with modular radio type approvals for various countries, including USA (FCC), Canada (IC/ISED) and Japan (MIC), and are in compliance with the relevant EN standards (including EN 300 328 v2.2.2) for the conformity with the directives and regulations in EU and UK.
