5. Power Consumption
Table.5.1 Power Consumption
Parameters Min Classical Max Unit
RX 11b /g/n, HT20 - - 65 mA
TX 11b, 1Mbps @21dBm - 370
TX 11g, 54Mbps @19dBm - - 320 mA
TX 11n, HT20, MCS7, @18.5dBm - - 300 mA
Modem-sleep, CPU is powered on @80MHz - 15 - mA
Light-sleep - 140 - uA
Deep-sleep, RTC timer + RTC memory - 5 - uA
Power off, CHIP_PU is set to low level - 1 0 uA
The peak current consumption of ESPC2-12 exceed 400mA when the module start work (RF calibration
work consumes maximum current). Therefore, the recommended power supply is no less than 500mA.
Note:
1. Active Mode: CPU and RF are all turned on.
2. Modem-sleep Mode: CPU is turned on. RF and baseband are turned off, but the communication is still
connected.
3. Light-sleep Mode: CPU is turned off. RTC/external interrupt/MAC can wake up the chip. The
communication is still connected.
4. Deep-sleep Mode: Only RTC is turned on.
6. Wi-Fi RF Characteristics
The data in the following table is gotten when voltage is 3.3V in the indoor temperature environment.
