DS1500/DS1510
25 of 25
NOTES:
1. Voltage referenced to ground.
2. Outputs are open.
3. The IRQ , PWR , and RST outputs are open drain.
4. Battery switch over occurs at the battery terminal voltage level.
5. Wakeup kickstart timeout generated only when the oscillator is enabled and the countdown chain is
not reset.
6. tDR is the amount of time that the internal battery can power the internal oscillator and internal
registers of the DS1510. As such tDR is specified with VCCO floating. If VCCO is powering an external
SRAM, an auxiliary battery should be connected to the VBAUX pin. The auxiliary battery should be
sized such that it can power the external SRAM for the tDR period.
7. If VPF is less than VBAT and VBAUX, the device power is switched from VCCI to the greater of VBAT and
VBAUX when VCCI drops below VPF. If VPF is greater than VBAT and VBAUX, the device power is
switched from VCCI to the larger of VBAT and VBAUX when VCCI drops below the larger of VBAT and
VBAUX.
8. 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
oC. Post solder cleaning with water washing techniques is acceptable, provided that
ultrasonic vibration is not used.
9. Value for voltage and currents is from the VCCI input pin to the VCCO pin.
10. Value for voltage and currents is from the VBAT or VBAUX input pin to the VCCO pin.
11. IBAT1 and IBAT2 are specified with VCCO floating and do not include any RAM current.
12. These parameters are sampled with a 5 pF load and are not 100% tested.
