Notes:

1. These are the recommended and tested operating conditions. Proper device operation outside of these conditions

is not guaranteed.

2. This voltage is the input to the ﬁlter discussed in Section 1.9.2, “PLL Power Supply Filtering” and not necessarily

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

3. 1.6 V nominal. Operation at core voltages up to 1.8 V is supported, but the power consumption given in Table 7

must be adjusted correspondingly by the formula: P = C V 2 f, where P is the power consumption, C is a constant,

V is the core voltage, and f is the core frequency.
