Note 1: 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
bandwidth being used. RX current is affected by connection distance.
2: Power Save current is current consumed during periods of “stand-by” 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).
