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 TA and the junction temperature TJ. For power dissipation
A.1.8 Power Dissipation and Thermal Characteristics
Power dissipation and thermal characteristics are closely related. The user must assure that the maximum
operating junction temperature is not exceeded. The average chip-junction temperature (TJ)in °C can be
obtained from:

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.
