Description of Device States

The ATWINC15x0B has several device states:

The following pins are used to switch between the ON and Power_Down states:

In the ON states, VDDIO is ON and CHIP_EN is high (at VDDIO voltage level). To switch between the ON states and Power_Down state CHIP_EN has to change between high and low (GND) voltage. When VDDIO is OFF and CHIP_EN is low, the chip is powered off with no leakage (for more information, refer to Restrictions for Power States).
