37.2.1 Absolute Maximum Ratings
Stresses beyond those listed in Table 37-35 on page 103 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 opera-
tional sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
Table 37-35. Absolute maximum ratings.
37.2.2 General Operating Ratings
The device must operate within the ratings listed in Table 37-36 in order for all other electrical characteristics and typical
characteristics of the device to be valid.
Table 37-36. General operating conditions.
Table 37-37. Operating voltage and frequency.
The maximum CPU clock frequency depends on V
CC
. As shown in Figure 37-8 the Frequency vs. V
CC
curve is linear
between 1.8V < V
CC
<2.7V.
