NOTES:
3. IRQ/FOUT Inactive.
4. VIL = VDD x 0.1, VIH = VDD x 0.9, fSCL = 400kHz
5. VDD > VBAT +VBATHYS
6. Bit BSW = 0 (Standard Mode), ATR = 00h, VBAT ≥1.8V
7. Specified at +25°C.
8. In order to ensure proper timekeeping, the VDD SR- specification must be followed.
9. Parameter is not 100% tested.
10. 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.
11. These are I2C specific parameters and are not directly tested, however they are used during device testing to validate device
specification.
12. 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.
