3. FUNCTIONAL DESCRIPTION
Power mode Description Power consumption
Modem-sleep The CPU is powered on.
Max speed 240 MHz: 30 mA ~ 50 mA
Normal speed 80 MHz: 20 mA ~ 25 mA
Slow speed 2 MHz: 2 mA ~ 4 mA
Light-sleep - 0.8 mA
Deep-sleep
The ULP co-processor is powered on. 150 µA
ULP sensor-monitored pattern 100 µA @1% duty
RTC timer + RTC memory 10 µA
Hibernation RTC timer only 5
µ
A
Power off CHIP_PU is set to low level, the chip is powered off 0.1 µA
Note:
• When Wi-Fi is enabled, the chip switches between Active and Modem-sleep mode. Therefore, power consumption
changes accordingly.
• In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load and
the peripherals used.
• During Deep-sleep, when the ULP co-processor is powered on, peripherals such as GPIO and I2C are able to
work.
• When the system works in the ULP sensor-monitored pattern, the ULP co-processor works with the ULP sensor
periodically; ADC works with a duty cycle of 1%, so the power consumption is 100 µA.
