NOTES:
1) All voltages are referenced to ground.
2) Logic 1 voltages are specified at a source current of 1mA.
3) Logic 0 voltages are specified at a sink current of 4mA.
4) ICC is specified with the DQ pin open.
5) ICC1 is specified with VCC at 5.0V and RST = GND.
6) Measured at VIH = 2.0V or VIL = 0.8V.
7) Measured at VOH = 2.4V or VOL - 0.4V.
8) Load capacitance = 50pF.
9) Battery trip point is the point at which the VCC powered counter and the serial port stops operation.
The battery trip point drops below the minimum once the internal lithium energy cell is exhausted.
10) The expected tDR is defined as accumulative time in the absence of VCC with the clock oscillator
running.
11) 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.
