1 _{Functional operating conditions are given in the DC electrical specifications. Absolute maximum ratings are stress ratings only,}
and functional operation at the maxima is not guaranteed. Stress beyond the listed maxima may affect device reliability or
cause permanent damage to the device.
2 _{Voltage overshoots during a high-to-low or low-to-high transition must not exceed 10 seconds per instance.}
3 _{2.0 V for 10 hours cumulative time, 1.2 V +10% for time remaining.}
4 _{5.3 V for 10 hours cumulative time, 3.3 V +10% for time remaining.}
5 _{6.4 V for 10 hours cumulative time, 5.0 V +10% for time remaining.}
6 _{VRC cannot be 100mV higher than VDDA. VDDSYN and VDD33 cannot be 100 mV higher than VRC.}
7 _{All functional non-supply I/O pins are clamped to VSS and VDDEx.}
