Stresses beyond those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. These are stress rat-
ings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Electrical Characteristics
(Vbat=3V -5.5V, CVa=4.7µF, CVrtc=0.22µF, CVcore=CVm=CVref=CVtcxo=CVsim=CVio=2.2µF, minimum
loads applied on all outputs, unless otherwise noted. Typical values are at TA=+25°C.)
