Attention:
① Modem-Sleep is used for the application requiring CPU always in operating state such as PWM or I2S
applications etc. When maintaining Wi-Fi connection, it is allowed to turn off Wi-Fi Modem circuit to save
power consumption according to 802.11 standard (such as U-APSD) when there is no data transmission. For
example, in the configuration ofDTIM3, it will wake up for 3ms to receive Beacon packet fromAP after sleeping
every 300ms, and the averange current is about 15mA.
② Light-Sleep is used for the application with CPU suspendable such as Wi-Fi switch. When maintaining Wi-Fi
connection, it is allowed to turn off Wi-Fi Modem circuit and suspend CPU to save power consumption
according to 802.11 standard (such as U-APSD) when there is no data transmission. For example, in the event
of DTIM3, it will wake up for 3ms to receive Beacon packet from AP after sleeping every 300ms, and the
averange current will be about 9mA.
③ Deep-Sleep is used for the application without the need to always maintain Wi-Fi connection and transmitting
one data packet for a long time such as the sensor measuring temperature every 100s. For example, it will wake
up for 0.3s - 1s every 300s and connect to AP to transmit data, and the averange current may be far smaller than
1mA.
