NOTES:
2. FT/OUT inactive.
3. LPMODE = 0 (default).
4. In order to ensure proper timekeeping, the VDD SR- specification must be followed.
5. Typical values are for T = +25°C and 3.3V supply voltage.
6. Limits should be considered typical and are not production tested.
7. These are I2C specific parameters and are not tested, however, they are used to set conditions for testing devices to validate specification.
8. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by
characterization and are not production tested.
