† 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. The JTAG fuse-blow voltage, VFB, is allowed to exceed the absolute maximum rating. The voltage is applied

to the TEST pin when blowing the JTAG fuse.

NOTES:

1. In LF mode, the LFXT1 oscillator requires a watch crystal. A 5.1M

Ω resistor from XOUT to VSS is recommended when VCC <

2.5 V. In XT1 mode, the LFXT1 and XT2 oscillators accept a ceramic resonator or crystal up to 4.15MHz at VCC ≥ 2.2 V. In XT1 mode,

the LFXT1 and XT2 oscillators accept a ceramic resonator or crystal up to 8MHz at VCC ≥ 2.8 V.

2. In LF mode, the LFXT1 oscillator requires a watch crystal. In XT1 mode, LFXT1 accepts a ceramic resonator or a crystal.
