6.3.2 Embedded reset and power control block characteristics
The parameters given in the following table are derived from the tests performed under the
conditions summarized in
Table 14 .
T
J
Junction temperature range
6 suffix version –40 105
°C
7 suffix version –40 110
1. When the ADC is used, refer to Table 56: ADC characteristics .
2. 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 up to 140 mV in operation.
3. To sustain a voltage higher than VDD+0.3V, the internal pull-up/pull-down resistors must be disabled.
4. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
J
max (see Table 72: Thermal characteristics
on page 128 ).
5. In low-power dissipation state, T
A
can be extended to -40°C to 105°C temperature range as long as T
J
does not exceed T
J
max (see Table 72: Thermal characteristics on page 128 ).
