Introduction#

Optimizing power consumption is essential for battery-powered wireless devices. Depending on the application, a device might stay idle for long or very short periods. During these idle periods, you can configure the device to enter Sleep mode to conserve battery power. The SiWx917 wireless device delivers an ultra‑low‑power Wi‑Fi® and Bluetooth® solution designed for applications that require long battery life without compromising wireless performance or connectivity.

This application note provides a technical overview of the SiWx917 power‑save modes and presents verified current‑consumption data for various power modes and states. It also explains how to validate the datasheet power numbers using reference examples for both SiWx917 SoC and SiWx917 NCP devices.
