Note:
1. Conditions: VBAT = 3.3V, VDDIO = 3.3V, at 25°C.
2. Current consumption mentioned for these states is the sum of current consumed in VDDIO and
VBAT voltage rails.
When power is not supplied to the device (DC/DC converter output and VDDIO are OFF, at ground
potential), voltage cannot be applied to the ATWINC3400-MR210CA module pins because each pin
contains an ESD diode from the pin to supply. This diode turns on when voltage higher than one diode-
drop is supplied to the pin.
If voltage must be applied to the signal pads when the chip is in a low-power state, the VDDIO supply
must be ON, so the Power_Down state must be used. Similarly, to prevent the pin-to-ground diode from
turning ON, do not apply voltage that is more than one diode-drop below the ground to any pin.
