XMEGA B3 [DATASHEET]
8074D–AVR–08/2013
36. Electrical Characteristics
All typical values are measured at T = 25C unless other temperature condition is given. All minimum and maximum
values are valid across operating temperature and voltage unless other conditions are given.
36.1 Absolute Maximum Ratings
Stresses beyond those listed in Table 36-1 on page 70 under may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or other conditions beyond those indicated in the
operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended
periods may affect device reliability.
Table 36-1. Absolute maximum ratings.
36.2 General Operating Ratings
The device must operate within the ratings listed in Table 36-2 on page 70 in order for all other electrical characteristics
and typical characteristics of the device to be guaranteed and valid.
Table 36-2. General operating conditions.
Table 36-3. Operating voltage and frequency.
