8.1 Operating Conditions<br />
Table 8-1 shows voltage, frequency, <strong>and</strong> temperature specifications for the applications processor<br />
for four different ranges. The temperature specification for each range is constant; the frequency<br />
range is operation voltage dependent. On a prototype design, the VCC/PLL_VCC regulator should<br />
have a range from 0.85 V to 1.65 V. PLL_VCC <strong>and</strong> VCC must be connected together on the board<br />
or driven by the same supply.<br />

NOTE: When VCCN=2.5 V, the I/O signals that are supplied by VCCN are 2.5 V tolerant only. Do not apply 3.3 V to any pin<br />
supplied by VCCN in this case.<br />
