Operating Conditions
Unless otherwise noted, the following conditions apply to all parametric data. Refer to the temperature
rating of the device (C, V, M) with respect to ambient temperature (TA) and junction temperature (TJ). For
power dissipation calculations refer to Section 3.6, “Power Dissipation and Thermal Characteristics.”
3.4.1
Input/Output Pins
The I/O pins operate at a nominal level of 3.3 V to 5 V. This class of pins is comprised of the clocks, control
and general purpose/peripheral pins. The internal structure of these pins is identical; however, some
functionality may be disabled (for example, for analog inputs the output drivers, pull-up/down resistors
are permanently disabled).
