D305 IV REF Internal Voltage Reference 0.57 0.6 0.63 V For devices without
BGSEL<1:0>
1.14 1.2 1.26 V BGSEL<1:0> = 00

Note 1: Response time measured with one comparator input at (V DD – 1.5)/2, while the other input transitions
from V
SS to V DD .
2: These parameters are characterized but not tested.
3: The Comparator module is functional at V BORMIN < V DD < V DDMIN , but with degraded performance. Unless
otherwise stated, module functionality is tested, but not characterized.
