Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 5. The LFXT1 oscillator in LF-mode requires a resistor of 5.1 MΩ from XOUT to VSS when VCC <2.5 V.
The LFXT1 oscillator in XT1-mode accepts a ceramic resonator or a crystal frequency of 4 MHz at VCC ≥ 2.2 V.
The LFXT1 oscillator in XT1-mode accepts a ceramic resonator or a crystal frequency of 8 MHz at VCC ≥ 2.8 V.
6. The LFXT1 oscillator in LF-mode requires a watch crystal.
The LFXT1 oscillator in XT1-mode accepts a ceramic resonator or a crystal.
7. The cumulative program time must not be exceeded during a segment-write operation.
