Note 2: Limits are 100% tested at TA = +25°C and TA = +85°C. Limits over the operating temperature range and relevant supply
voltage range are guaranteed by design and characterization. Typical values are not guaranteed.
Note 3: Includes the temperature conversion current (averaged).
Note 4: Does not include RST leakage if VCC < VPF.
Note 5: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set.
Note 6: The state of RST does not affect the I2C interface or RTC functions.
Note 7: Interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with standard mode
I2C timing.
Note 8: CB = total capacitance of one bus line in picofarads.
Note 9: Guaranteed by design and not 100% production tested.
