NOTES:
1. All voltages are referenced to ground.
2. Typical values are at 25
°C and nominal supplies.
3. Outputs are open.
4. Value for voltage and currents is from the VCCI input pin to the VCCO pin.
5. Write protection trip point occurs during power fail prior to switchover from VCC to VBAT.
6. Value for voltage and currents is from the VBAT input pin to the VCCO pin.
7. Applies to the AD0-AD7 pins, and the SQW pin when each is in a high impedance state.
8. The IRQ pin is open drain.
9. Measured with a load of 50 pF + 1 TTL gate.
10. Wakeup kickstart timeout generated only when the oscillator is enabled and the countdown chain is
not reset.
11. VSW is determined by the larger of VBAT and VBAUX.
12. ZCE is an average input to output impedance as the input is swept from GND to VCCI and less than
4 mA is forced through ZCE.
13. The DS1693 will keep time to an accuracy of
±1 minute per month during data retention time for the
period of tDR.
14. tDR is the amount of time that the internal battery can power the internal oscillator and internal
registers of the DS1693. As such, tDR is specified with VCCO floating. If VCCO is powering an external
SRAM, an auxiliary battery must be connected to the VBAUX pin. The auxiliary battery should be sized
such that it can power the external SRAM for the tDR period.
15. The CEI pin has an internal pull-up of 60 k.
16. The PSEL pin has an internal pull-down of 60 k
.
17. For industrial grade parts, IBAT (with OSC off) limit increases to 250 nA.
18. Real-Time Clock Modules can be successfully processed through conventional wave-soldering
techniques as long as temperature exposure to the lithium energy source contained within does not
exceed +85
°C. Post-solder cleaning with water washing techniques is acceptable, provided that
ultrasonic vibration is not used.
