Note:

When the device enters into standby mode, the LP pads have the input buffer switched-on.

As a consequence, if the pad input voltage VIN is VSS<VIN<VDD_HV, an additional

consumption can be measured in the VDD_HV domain. The highest consumption can be

seen around mid-range (VIN ~=VDD_HV/2), 2-3mA depending on process, voltage and

temperature.

This situation may occur if the PAD is used as a ADC input channel, and VSS<VIN<VDD_HV.

The applications should ensure that LP pads are always set to VDD_HV or VSS, to avoid

the extra consumption. Please refer to the device pinout IO definition excel file to identify the

low-power pads which also have an ADC function.

I/O output DC characteristics

Figure 4 provides description of output DC electrical characteristics.

4. In the range from WFI (max) to WNFI (min), pulses can be filtered or not filtered, according to operating temperature and

voltage. Refer to the device pinout IO definition excel file for the list of pins supporting the wakeup filter feature.
