Note:

• * Among the ESP32 series of SoCs, ESP32-D0WD-V3, ESP32-D0WDQ6-V3, ESP32-D0WD, and ESP32-D0WDQ6

have a maximum CPU frequency of 240 MHz, ESP32-D2WD, ESP32-S0WD, and ESP32-U4WDH have a maximum

CPU frequency of 160 MHz.

• When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. 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

operate.

• When the system works in the ULP sensor-monitored pattern, the ULP co-processor works with the ULP sensor

periodically and the ADC works with a duty cycle of 1%, so the power consumption is 100 µA.
