NOTES:
7. RESET Inactive (no reset).
8. VIL = VDD x 0.1, VIH = VDD x 0.9, fSCL = 400kHz.
9. VRESET = 2.63V (VDD must be greater than VRESET), VBAT = 0V.
10. Bit BSW = 0 (Standard Mode), ATR = 00h, VBAT ≥1.8V.
11. Specified at +25°C.
12. In order to ensure proper timekeeping, the VDD SR- specification must be followed.
13. Parameter is not 100% tested.
14. tWC is the minimum cycle time to be allowed for any non-volatile Write by the user, it is the time from valid STOP condition at the end of Write
sequence of a serial interface Write operation, to the end of the self-timed internal non-volatile write cycle.
15. These are I2C specific parameters and are not directly tested, however they are used during device testing to validate device specification.
16. 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.
