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) IBAT is specified with VCC < VBAT and VBAT within DC recommended operating conditions.
7) Measured at VIH = 2.0V or VIL = 0.8V.
8) Measured at VOH = 2.4V or VOL = 0.4V.
9) Load capacitance = 50pF.
10) Specified as the load capacitance for which the crystal frequency is guaranteed (see crystal
manufacturer’s data sheet).
11) Leakage current is the amount of current consumed from the battery when VCC is not present and the
oscillator is turned off.
12) Using a crystal on X1 and X2.
