5.0 ELECTRICAL CHARACTERISTICS
Table 5-1 , Table 5-2 , Table 5-3 and Table 5-4 provide the absolute maximum ratings, recommended operating
conditions, current consumption and the DC characteristics for digital IO pins of the module.
TABLE 5-3: CURRENT CONSUMPTION

(NOMINAL CONDITIONS: 25°C, VDD = 3.3V)
TABLE 5-1: ABSOLUTE MAXIMUM RATINGS
(1)
Symbol Description Max Rating Units
VDD Voltage on VDD with respect to GND -0.3 to 4.0 V
V
DI
Min. Minimum digital input voltage -0.3 V

DO
Max. Maximum digital input voltage VDD+0.3 V
RF
IN
Maximum RF input (referenced to 50 ohms) +10 dBm
Note 1: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure above maximum rating conditions
for extended periods may affect device reliability.

Note 1: Current Consumption values represent Typical Peak currents. Wi-Fi applications typically operate at less than
85% TX duty cycle. TX current is dependent on such criteria as transmit power setting, transmit data rate, and
bandwidth used. RX current is affected by connection distance.
2: Transmit current consumption at power output levels listed in Table 5-6 .
