The power and clock management system in nRF7000 is optimized for ultra-low power applications to ensure maximum power efficiency.

Power states
nRF7000 has three power states: Shutdown, Sleep, and Active.
Power state operation
Apart from transitions in or out of Shutdown state through the BUCKEN pin, all transitions between Sleep and Active states are automatic and do not rely on any control pin assertion or de-assertion.
Clock accuracy considerations
The crystal oscillator is active during normal operation, and is the clock reference for the RF synthesizer, the Analog-to-Digital Converter (ADC)/Digital-to-Analog Converter (DAC) sample clocks, and the baseband logic. The Real-time Clock (RTC) is active during sleep state, and is used to run the wakeup timer used as part of Wi-Fi® Power Save. The crystal oscillator is inactive during sleep.
