AC CHARACTERISTICS
Standard Operating Conditions (see Note 2): 3.0V to 3.6V
(unless otherwise stated)
Operating temperature -40°C  T
A  +85°C for Industrial
-40°C  T

Param. Symbol Characteristic Min. Typ. Max. Units Conditions
VR310 T
SET Settling Time — 1 10 s (Note 1)
Note 1: Settling time is measured while CVRR = 1 and the CVR<3:0> bits transition from ‘0000’ to ‘1111’.
2: Device is functional at VBORMIN < VDD < VDDMIN, but will have degraded performance. Device functionality
is tested, but not characterized. Analog modules: ADC, op amp/comparator and comparator voltage
reference, will have degraded performance. Refer to Parameter BO10 in Table 33-12 for the minimum and
maximum BOR values.
