Both crossing 70% of VDD. 600 ns tDH Output Data Hold Time From SCL falling edge crossing 30% of VDD, until SDA enters the 30% to 70% of VDD window. 0ns Cb Capacitive Loading of SDA or SCL Total on-chip and off-chip. 10 400 pF Cpin SDA, and SCL Pin Capacitance 10 pF tWC Non-volatile Write Cycle Time 12 20 ms 10 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), 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.
