NOTES:
1. WE is high for a read cycle.
2. OE = VIH or VIL. If OE = VIH during write cycle, the output buffers remain in a high impedance state.
3. tWP is specified as the logical AND of CE and WE . tWP is measured from the latter of CE or WE
going low to the earlier of CE or WE going high.
4. tDH, tDS are measured from the earlier of CE or WE going high.
5. These parameters are sampled with a 50pF load and are not 100% tested.
6. If the CE low transition occurs simultaneously with or later than the WE low transition in Write
Cycle 1, the output buffers remain in a high impedance state during this period.
7. If the CE high transition occurs prior to or simultaneously with the WE high transition, the output
buffers remain in a high impedance state during this period.
8. If WE is low or the WE low transition occurs prior to or simultaneously with the CE low transition,
the output buffers remain in a high impedance state during this period.
9. The expected tDR is defined as cumulative time in the absence of VCC with the clock oscillator
running.
10. tWR is a function of the latter occurring edge of WE or CE .
11. tDH and tDS are a function of the first occurring edge of WE or CE .
12. RST (Pin1) has an internal pullup resistor.
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.
