Power Consumption#

See the SiWG917 Data Sheet and the SiWG917 Typical Current Consumption section in Low-Power Application Note for the power numbers of each power state.

Sample Applications in Wiseconnect SDK#

See the directory in SDK mcu_powerstate in the WiSeConnect SDK demonstrating the PS1, PS0, PS4/PS3/PS2 sleep and active states.

Note: This application is designed to validate the MCU's power consumption values specified in the data sheet, and therefore contains meticulous optimizations. This application should not be taken as reference for a real-time use case project bring up. This application does not support wake-up sources.

The sl_si91x_power_manager_tickless_idle application demonstrates the Power Manager service APIs, active-state transitions (PS4, PS3, and PS2), standby-state transitions (PS4, PS3, and PS2) and sleep-wakeup (PS4, PS3, PS2, and PS1 sleep with RAM retention) with Tickless Idle mode.

The wifi_station_ble_provisioning_aws application demonstrates an integrated use-case involving Wi-Fi, Bluetooth Low Energy (BLE), and peripheral interfaces, in conjunction with the Power Manager for managing sleep and wake-up transitions via designated wake-up sources.

To measure the power consumption of only Network Wireless Processor (NWP) core, you can configure M4 in PS0 (which is without any RAM retention).

Refer to the System-on-Chip (SoC) low-power compatibility matrix in Low-Power Application Note for the combinations of M4 and NWP power states that are valid and supported.
