Caution:
• Operating the chip in excess of the absolute maximum rating may result in permanent damage.
• Order of turning on 1.5 V power (Vcc, Vcc-PLL1, Vcc-PLL2) and 3.3 V power (VccQ, VccQ-
RTC):
1. The 3.3 V power and the 1.5 V power should be turned on simultaneously or the 3.3 V
power should be tuned on first. When the 3.3 V is turned on first, turn on the 1.5 V power
within 1 ms. It is recommended that this interval will be as short as possible.
2. Until voltage is applied to all power supplies and a low level is input at the RESETP pin,
internal circuits remain unsettled, and so pin states are also undefined. The system design
must ensure that these undefined states do not cause erroneous system operation.
3. When the power is turned on, make sure that the voltage of the 1.5 V power is lower than
that of the 3.3 V power.
