† _{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.
NOTE: All voltages referenced to VSS.

1. 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.
2. The LFXT1 oscillator in LF-mode requires a watch crystal. The LFXT1 oscillator in XT1-mode accepts a ceramic resonator or crystal.
