4.2.9 Low Power Modes
It supports Ultra-low power consumption with multiple power modes to reduce the system energy consumption.
•
Dynamic Voltage and Frequency Scaling
•
Low Power (LP) mode with only the host interface active
•
Deep sleep (ULP) mode with only the sleep timer active
– with and without RAM retention
•
Wi-Fi standby associated mode with automatic periodic wake-up
•
Automatic clock gating of the unused blocks or transit the system from Normal to LP or ULP modes
4.2.9.1
ULP Mode
In Ultra Low Power mode, the deep sleep manager has control over the other subsystems and processors and
controls their active and sleep states. During deep sleep, the always-on logic domain operates on a lowered supply
and a 32 kHz low-frequency clock to reduce power consumption. The ULP mode supports the following wake-up
options:
•
Timeout wakeup
– Exit sleep state after programmed timeout value.
