Note 2: Limits at -40°C are guaranteed by design and not production tested.
Note 3: All voltages are referenced to ground.
Note 4: Measured at VIH = 0.8 x VCC or VIL = 0.2 x VCC, 10ns rise/fall time, DOUT = no load.
Note 5: Current is the averaged input current, which includes the temperature conversion current. CRATE1 = CRATE0 = 0.
Note 6: The RST pin has an internal 50k
Ω (nominal) pullup resistor to VCC.
Note 7: Measured at VOH = 0.8 x VCC or VOL = 0.2 x VCC. Measured from the 50% point of SCLK to the VOH minimum of DOUT.
Note 8: With 50pF load.
Note 9: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage range of
0V
≤ VCC ≤ VCC(MAX) and 2.3V ≤ VBAT ≤ VBAT(MAX).
Note 10: This delay only applies if the oscillator is enabled and running. If the EOSC bit is 1, tREC is bypassed and RST immediately
goes high.
Note 11: 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.
