6. This LVD/HVD disabled supply voltage condition only applies after LVD/HVD are disabled by the application during the

reset sequence, and the LVD/HVD are active until that point.

7. The pad are operative till 3.0V full performance. The IRC oscillator is supplied by this pin and it is setting the min voltage

limit.

8. FEC will be used only in 3.3V mode. In 5V mode the segment is a general IO segment with the same characteristics of

IO_MAIN.

9. MSC will be used only in 3.3V mode. In 5V mode the segment is a general IO segment with the same characteristics of

IO_MAIN.

10. If XOSC is enabled via DCF_UTEST_Miscellaneous[XOSC_EN], V

DD_HV_IO_JTAG

 must be within the operating range

before RESET pin is released.

11. JTAG will be used only in 3.3V mode. In 5V mode the segment is a general IO segment with the same characteristics of

IO_MAIN.

12. The startup of flash regulator and memory initialization immediately after Phase0 of reset sequence could cause a drop of

the PMC supply. No LVD event will be generated as during this time the LVD monitors are not enabled.

13. V

DDSTBY

 supply must be present before and after power up/down of the device supplies and the ramp rate should be less

than 33.3 kV/s.

14. RAM retention is not guaranteed below 1.3 V, but no effect on RAM operation for voltages below 1.3 V when V

DD_LV

 is

above the minimum value.

15. For supply voltages between 3.6V and 4.5V there will be no guaranteed precision of ADC (accuracy/linearity). ADC will

recover to a fully functional state when the voltage rises above 4.5V.

16. V

DD_HV_ADV_SD

 must be higher or equal than the V

DD_HV_ADV_SAR

 supply to guarantee full performance. It is recommended

to connect the V

DD_HV_ADV_SD

 to V

DD_HV_ADV_SAR

 at board level.

17. Temperature Sensor and its associated Band-Gap reference are supplied by this pin. The temperature sensor

performance is guaranteed only between 4.5 V and 5.5 V.

18. Full device lifetime without performance degradation.
19. I/O and analog input specifications are only valid if the injection current on adjacent pins is within these limits. See the

absolute maximum ratings table for maximum input current for reliability requirements.

20. The I/O pins on the device are clamped to the I/O supply rails for ESD protection. When the voltage of the input pin is

above the supply rail, current will be injected through the clamp diode to the supply rail. For external RC network
calculation, assume typical 0.3 V drop across the active diode. The diode voltage drop varies with temperature. For more
information, see the device characterization report.

21. Sum of all controller pins (including both digital and analog) must not exceed 200 mA. A V

DD_HV_IO

 power segment is

defined as one or more GPIO pins located between two V

DD_HV_IO

 supply pins.

22. The average current values given in the "I/O pad current specifications" section should be used to calculate total I/O

segment current.
