† _{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 1: All voltages referenced to V_SS. The JTAG fuse-blow voltage, V_FB, is allowed to exceed the absolute maximum rating. The voltage is
applied to the TDI/TCLK pin when blowing the JTAG fuse.

NOTES: 1. It is recommended to power AV_CC and DV_CC from the same source. A maximum difference of 0.3 V between AV_CC and DV_CC can
be tolerated during power up and operation.
2. The minimum operating supply voltage is defined according to the trip point where POR is going active by decreasing supply voltage.
POR is going inactive when the supply voltage is raised above minimum supply voltage plus the hysteresis of the SVS circuitry.
3. The LFXT1 oscillator in LF-mode requires a watch crystal.
