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) with regards to the ambient
temperature T_A and the junction temperature T_J. For power dissipation
calculations refer to A.1.8 Power Dissipation and Thermal Characteristics.

NOTES:
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 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.
