Note 1:
Limits at -40°C are guaranteed by design and not production tested.
Note 2:
All voltages are referenced to ground.
Note 3:
Measured at V

, 10ns rise/fall time, DOUT = no load.
Note 4:
Current is the averaged input current, which includes the temperature conversion current. CRATE1 = CRATE0 = 0.
Note 5:
The
RST
pin has an internal 50k
(nominal) pullup resistor to V
CC
.
Note 6:

. Measured from the 50% point of SCLK to the V
OH
minimum of DOUT.
Note 7:
With 50pF load.
Note 8:
The parameter t
OSF
is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage range of
0V

Note 9:
This delay only applies if the oscillator is enabled and running. If the
EOSC
bit is 1, t
REC
is bypassed and
RST
immediately
goes high.
Note 10:
Guaranteed by design and not production tested.
WARNING: Negative undershoots below -0.3V while the part is in battery-backed mode may
cause loss of data.
