Notes:

1. These are the recommended and tested operating conditions.

2. This voltage is the input to the filter discussed in Section 9.2.2, “PLL Power Supply Filtering,” and not necessarily the voltage

at the AVDD pin, which may be reduced from VDD by the filter.

3. Some early devices supported voltage and frequency derating whereby VDD (and AVDD) could be reduced to reduce power

consumption. This feature has been superseded and is no longer supported. See Section 5.3, “Voltage and Frequency

Derating,” for more information.

4. Caution: Power sequencing requirements must be met; see Section 9.2, “Power Supply Design and Sequencing”.

5. Caution: See Section 9.2.3, “Transient Specifications” for information regarding transients on this power supply.

6. For information on extended temperature devices, see Section 11.2, “Part Numbers Not Fully Addressed by This Document.”
