NOTES:
1. All voltage referenced to ground.
2. SDI should be taken to a logic high when V
3. SDI is deglitched to prevent accidental destruction. The pulse must be longer than t
4. Maximum operating I
5. Idle mode I
6. Stop mode I
7. Pin capacitance is measured with a test frequency—1 MHz, T
8. Crystal startup time is the time required to get the mass of the crystal into vibrational motion from the
