Note 5:
The external clock feeding into the circuit passes through the
oscillator before clocking the watchdog timer. Variation in the time-out
period is caused by phase errors which occur when the oscillator divides
the external clock by 64. The resulting variation in the time-out period is
64 plus one clock of jitter.
Note 6:
The input pins of CE IN, OSC IN and OSC SEL have weak internal
pull-ups which pull to the supply when the input pins are floating.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of device may be impaired.
Note 2:
All voltage values are with respect to GND.
Note 3:
For military temperature range parts, consult the factory.
Note 4:
The output pins of BATT ON, LOW LINE, PFO, WDO, RESET and
RESET have weak internal pullups of typically 3
μ
A. However, external pull-
up resistors may be used when higher speed is required.
