1. The average expected gain in power consumption when VOS = 0 compared to VOS = 1 is around 10% for the whole
temperature range, when the system clock frequency is between 30 and 144 MHz.
2. V

DDA
minimum value of 1.7 V is obtained when the device operates in reduced temperature range, and with the use of
an external power supply supervisor (refer to Section : Internal reset OFF).
3. When the ADC is used, refer to Table 67: ADC characteristics.
4. If V
REF+
pin is present, it must respect the following condition: V
DDA
-V
REF+
< 1.2 V.
5. It is recommended to power V
DD
and V
DDA
from the same source. A maximum difference of 300 mV between V
DD
and
V
DDA
can be tolerated during power-up and power-down operation.
6. To sustain a voltage higher than V
DD
+0.3, the internal pull-up and pull-down resistors must be disabled.
7. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
Jmax
.
8. In low-power dissipation state, T
A
can be extended to this range as long as T
J
does not exceed T
Jmax
.
