1. When RESET is released functionality is guaranteed down to VBOR0 Min.

2. When VDDmin is lower then 1.95 V, the SMPS operation mode is enabled by the BORH configuration to force SMPS bypass

mode, or the SMPS is not enabled.

3. This formula has to be applied only on the power supplies related to the IO structure described by the pin definition table.

Maximum I/O input voltage is the smallest value between min (VDD, VDDA) + 3.6 V and 5.5 V.

4. For operation with voltage higher than min (VDD, VDDA) + 0.3 V, the internal pull-up and pull-down resistors must be

disabled.

5. In low-power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax (see Section 7.3:

Thermal characteristics).
