Note 1:
Limits at -40°C are not production tested and are guaranteed by design.
Note 2:
RTC modules can be successfully processed through conventional wave-soldering techniques as long as temperature exposure to the
lithium energy source contained within does not exceed +85°C. Post-sold cleaning with water-washing techniques is acceptable,
provided that ultrasonic vibration is not used to prevent damage to the crystal.
Note 3:
Voltage referenced to ground.
Note 4:
Outputs are open.
Note 5:
The

RST
outputs are open drain.
Note 6:
If V

, the device power is switched from V
CC
to the greater of V
BAT
or V
BAUX
when V

drops below V

current. Using a 32,768Hz crystal connected to X1 and X2.
Note 8:
These parameters are sampled with a 5pF load and are not 100% tested.
Note 9:
t
DR
is the amount of time that the internal battery can power the internal oscillator and internal registers of the DS1511.
Note 10:
If the oscillator is not enabled, the startup time of the oscillator after V
CC1
is applied will be added to the wakeup/kickstart timeout.
Note 11:
Typical values are at +25°C, nominal (active) supply, unless otherwise noted.
