Restrictions for Power States

When no power supplied to the device, i.e., the DC/DC Converter output and VDDIO are both off (at ground

potential). In this case, a voltage cannot be applied to the device pins because each pin contains an ESD

diode from the pin to supply. This diode will turn on when voltage higher than one diode-drop is supplied to the

pin.

If a voltage must be applied to the signal pads while the chip is in a low power state, the VDDIO supply must

be on, so the SLEEP or Power_Down state must be used.

Similarly, to prevent the pin-to-ground diode from turning on, do not apply a voltage that is more than one

diode-drop below ground to any pin.

9.3 Power-Up/Down Sequence

The power-up/down sequence for ATWINC1500 is shown in Figure 9-2. The timing parameters are provided in

Table 9-3.

Notes

VBATT and VDDIO can rise simultaneously or can be

tied together. VDDIO must not rise before VBATT.
