Note 1: Sleep current is current consumed during periods of “standby” between DTIM beacons. The module will
awake 2 mS before a DTIM and turn on its receiver, and possibly its transmitter (if data is available for it).
2: IDD core is current consumed by the part not including the I/O consumption of the SPI port.
3: Current Consumption values represent Typical Peak currents, and the measured current conditions were
done with 85% duty cycle modulated signal. Wi-Fi applications typically operate at less than 85% TX duty
cycle. TX current is dependent on such criteria as transmit power setting, and transmit data rate and band-
width being used. RX current is affected by connection distance.
