Appendix A Electrical Characteristics
A.1.7 Operating Conditions
This section 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 calculations refer to Section A.1.8, âPower Dissipation and
Thermal Characteristicsâ.

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, âPower Dissipation and Thermal Characteristicsâ for more details about the relation between
ambient temperature TA and device junction temperature TJ.
