36.3.1 Absolute Maximum Ratings
Stresses beyond those listed in Table 36-1 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 36-65. Absolute maximum ratings.
36.3.2 General Operating Ratings
The device must operate within the ratings listed in Table 36-2 in order for all other electrical characteristics and typical
characteristics of the device to be valid.
Table 36-66. General operating conditions.
Table 36-67. Operating voltage and frequency.
The maximum CPU clock frequency depends on V

. As shown in Figure 36-1 the Frequency vs. V
CC
curve is linear
between 1.8V < V
