AC ELECTRICAL CHARACTERISTICS—I2C INTERFACE
(VCC or VBAT = +2.3V to +5.5V, TA = -45NC to +85NC, unless otherwise noted. Typical values are at VCC = +3.3V, VBAT = +3.0V,
and TA = +25NC, unless otherwise noted.) (Note 6, Figure 1)
Note 2: All voltages are referenced to ground.
Note 3: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set.
Note 4: Includes the temperature conversion current (averaged).
Note 5: This delay applies only if the oscillator is enabled. If the EOSC bit is 1, tREC is bypassed and RST immediately goes high.
The state of RST does not affect the I2C interface or RTC functions.
Note 6: Interface timing shown is for fast-mode (400kHz) operation. This device is also backward-compatible with standard mode
I2C timing.
Note 7: CB: Total capacitance of one bus line in picofarads.
Note 8: Guaranteed by design; not 100% production tested.
