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. .
2. This refers to the oscillator base frequency. Typical crystal & resonator tolerances are supported.
3. Please refer to Table A-25 for maximum bus frequency limits with frequency modulation enabled
4. 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.
NOTE
Using the internal voltage regulator, operation is guaranteed in a power
down until a low voltage reset assertion.
