1. When the ADC is used, refer to Table 54: ADC characteristics.

2. 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 operation.

3. To sustain a voltage higher than VDD+0.3 V, the internal pull-up/pull-down resistors must be disabled.

4. If TA is lower, higher PD values are allowed as long as TJ does not exceed TJ max (see Table 12: Thermal characteristics

on page 53).

5. In low power dissipation state, TA can be extended to this range as long as TJ does not exceed TJ max (see Table 12:

Thermal characteristics on page 53).
