1. V
2. Some modules may require a minimum frequency greater than dc for proper operation; see appropriate table for this
3. Minimum pulse width reset is guaranteed to be recognized. It is possible for a smaller pulse width to cause a reset.
1. Typical value reflect average measurements at midpoint of voltage range, 25 ×C only. See
2. No more than 10% duty cycle deviation from 50%.
3. Fundamental mode crystals only.
4. Consult crystal manufacturer’s data.
5. Not Required for high frequency crystals.
