A.1.7 Operating Conditions
This chapter describes the operating conditions of the device. Unless otherwise noted those conditions
apply to all the following data.
NOTE
Please refer to the temperature rating of the device (C, V, M) with regards to
the ambient temperature T_A and the junction temperature T_J. For power
dissipation calculations refer to Section A.1.8, “Power Dissipation and
Thermal Characteristics.”

1 _{The device contains an internal voltage regulator to generate the logic and PLL supply out of the I/O supply. The}
absolute maximum ratings apply when this regulator is disabled and the device is powered from an external source.
2 _{Please refer to Section A.1.8, “Power Dissipation and Thermal Characteristics,” for more details about the relation}
between ambient temperature T_A and device junction temperature T_J.
