The CPU is
powered on

240 MHz 30 ~ 68 mA
160 MHz 27 ~ 44 mA
Normal speed: 80 MHz 20 ~ 31 mA
Light-sleep — 0.8 mA
Deep-sleep
The ULP coprocessor is powered on
4
150 µA
ULP sensor-monitored pattern
5
100 µA @1% duty
RTC timer + RTC memory 10 µA
RTC timer only 5 µA
Power off CHIP_PU is set to low level, the chip is powered off 1 µA
1
The current consumption figures in Modem-sleep mode are for cases where the CPU is powered on and the
cache idle.
2
When Wi-Fi is enabled, the chip switches between Active and Modem-sleep modes. Therefore, current
consumption changes accordingly.
3
In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPU load
and the peripherals used.
4
During Deep-sleep, when the ULP coprocessor is powered on, peripherals such as GPIO and RTC I2C are
able to operate.
5
The ”ULP sensor-monitored pattern” refers to the mode where the ULP coprocessor or the sensor works
periodically. When ADC works with a duty cycle of 1%, the typical current consumption is 100 µA.

1
Device should operate in the center frequency range allocated by regional regulatory authorities.
Target center frequency range is configurable by software.
2
For the modules that use external antennas, the output impedance is 50 Ω. For other modules
without external antennas, the output impedance is irrelevant.
4.5.2 Transmitter Characteristics
Target TX power is configurable based on device or certification requirements. The default characteristics are
provided in Table 10.
