If IRROFF is set to VDD, this value can be lowered to 1.65 V when the device operates in a reduced temperature range.

When the ADC is used, refer to Table 61: ADC characteristics.

It is recommended to power VDD and VDDA from the same source. A maximum difference of 300 mV between VDD and

VDDA can be tolerated during power-up and power-down operation.

This parameter range must be respected for the full application range, taking into account the physical capacitor

characteristics and tolerance.

If TA is lower, higher PD values are allowed as long as TJ does not exceed TJmax.

In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJmax.
