Operating Modes

Operating Mode	Nom. Value	Unit
Modem Sleep (CPU active, Freq = 240 MHz, all RTC peripherals active)	32	mA
Modem Sleep (CPU active, Freq = 240 MHz, all RTC peripherals passive)	23	mA
Modem Sleep (CPU idle, Freq = 240 MHz, all RTC peripherals active)	28	mA
Modem Sleep (CPU idle, Freq = 240 MHz, all RTC peripherals passive)	20	mA
Modem Sleep (CPU active, Freq = 160 MHz, all RTC peripherals active)	24	mA
Modem Sleep (CPU active, Freq = 160 MHz, all RTC peripherals passive)	16	mA
Modem Sleep (CPU idle, Freq = 160 MHz, all RTC peripherals active)	21	mA
Modem Sleep (CPU idle, Freq = 160 MHz, all RTC peripherals passive)	14	mA
Modem Sleep (CPU active, Freq = 80 MHz, all RTC peripherals active)	20	mA
Modem Sleep (CPU active, Freq = 80 MHz, all RTC peripherals passive)	12	mA
Modem Sleep (CPU idle, Freq = 80 MHz, all RTC peripherals active)	18.4	mA
Modem Sleep (CPU idle, Freq = 80 MHz, all RTC peripherals passive)	10.5	mA
Light Sleep (Wi-Fi and SPI power off, all I/O pins high impedance)	750	µA
Deep Sleep (ULP active, ULP-FSM)	170	µA
Deep Sleep (ULP active, ULP-RISC-V)	190	µA
Deep Sleep (ULP periodically active, 1% duty cycle)	22	µA
Deep Sleep (RTC timer, RTC memory)	25	µA
Deep Sleep (RTC timer)	20	µA
Power Off	1	µA

In Modem Sleep modes, power consumption may increase depending on flash access.
In Deep Sleep (ULP active) modes, while the ULP coprocessor is running, internal peripherals such as GPIO and I2C can continue their operational activities.

RF Communication Modes (Wi-Fi)

Communication Mode	Peak Value	Unit
Transmitter (802.11b, 20 MHz, 1 Mbps, POUT = +19.5 dBm)	310	mA
Transmitter (802.11g, 20 MHz, 54 Mbps, POUT = +15 dBm)	220	mA
Transmitter (802.11n, 20 MHz, MCS7, POUT = +13 dBm)	200	mA
Transmitter (802.11n, 40 MHz, MCS7, POUT = +13 dBm)	160	mA
Receiver (802.11b/g/n, 20 MHz)	63	mA
Receiver (802.11n, 40 MHz)	68	mA

All measurements were performed at an ambient temperature of 25 °C with a 3.3 V supply voltage.
Transmitter mode measurements were conducted at a 100% duty cycle.
During receiver mode measurements, all peripherals were disabled and the CPU was idle.
