1. On devices in WLCSP64+2 package, if IRROFF is set to V
DD
, the supply voltage can drop to 1.7 V when the device
operates in the 0 to 70 °C temperature range using an external power supply supervisor (see Section 3.16).
2. When the ADC is used, refer to Table 66: ADC characteristics.
3. 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.
4. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
Jmax
.
5. In low-power dissipation state, T
A
can be extended to this range as long as T
J
does not exceed T
Jmax
.
