NOTES:
7. IRQ/FOUT Inactive.
8. VIL = VDD x 0.1, VIH = VDD x 0.9, fSCL = 400kHz
9. VDD > VBAT +VBATHYS
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. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
