BURST MODE TIMING WAVEFORM
NOTES:
1. All voltages are referenced to ground.
2. Typical values are at 25°C and nominal supplies.
3. Outputs are open.
4. Write protection trip point occurs during power-fail prior to switchover from VCC to VBAT.
5. Applies to the AD0-AD7 pins, and the SQW pin when each is in a high impedance state.
6. The IQR and PWR pins are open drain.
7. Measured with a load of 50 pF + 1 TTL gate.
8. Wakeup kickstart timeout generated only when the oscillator is enabled and the countdown chain is
not reset.
9. VSW is determined by the larger of VBAT and VBAUX.
10. The DS17287 will keep time to an accuracy of ±1 minute per month during data retention time for the
period of tDR.
11. tDR is the amount of time that the internal battery can power the internal oscillator and internal
registers of the DS17287.
12. IBAT1 and IBAT2 are measured at VBAT = 3.5V.
13. 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.
