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.
