Cautions:
• Operating the chip in excess of the absolute maximum rating may result in permanent damage.
• Order of turning on or off 1.9 V power (Vcc, Vcc – PLL1, Vcc – PLL2, Vcc – RTC) and 3.3 V
power (VccQ, AVcc):
1. The voltage of 1.9 V power should not be higher than that of 3.3 V power.
The period when only 3.3 V power is turned on should be less than 1 ms. This period
should be as short as possible.
2. Until voltage is applied to all power supplies, a high level is input at the CA pin, and a low
level is input at the RESETP pin, and CKIO clocks are equal to or below 4 clocks, 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. When the CA
pin is at a low level, the low level of the RESETP pin is not accepted.
