POWER-UP/DOWN CHARACTERISTICS
(TA = -40°C to +85°C, unless otherwise noted.)
CAPACITANCE
(TA = +25°C, unless otherwise noted.)
CRYSTAL PARAMETERS
Note 2: Voltage referenced to ground.
Note 3: Limits at TA = -40°C are guaranteed by design and not production tested.
Note 4: CE = VCC, VSCLK = VCC to GND, IOUT = 0mA, trickle charger disabled.
Note 5: CE = GND, IOUT = 0mA, EOSC = EGFIL = DOSF = 0, trickle charger disabled.
Note 6: VCC = 0V, EGFIL = 0, DOSF = 1.
Note 7: VCC = 0V, EGFIL = 1, DOSF = 0.
Note 8: Applies to INT0 and INT1.
Note 9: The parameter tOSF is the period of time the oscillator must be stopped for the OSF flag to be set.
Note 10: Guaranteed by design; not 100% production tested.
