Standard Operating Conditions: 3.0V to 3.6V (see Note 3)
(unless otherwise stated)
Operating temperature -40°C  T
A  +85°C for Industrial
-40°C  T

——10s
Note 1: Parameters are characterized but not tested.
2: Response time is measured with one comparator input at (V
DD – 1.5)/2, while the other input transitions
from VSS to VDD.
3: Device is functional at V
BORMIN < VDD < VDDMIN. Analog modules: ADC, Comparator and DAC will have
degraded performance. Device functionality is tested but not characterized. Refer to Parameter BO10 in
Table 32-11 for the minimum and maximum BOR values.
