The condition of power (VDD=3.3V, 2.5V, 1.5V) rising and falling
(1)Power Supply rising
These contents are the important items which influence the reliability guarantee of the IC.
It is necessary to satisfy the following condition.

*note1
Such the power terminal are embedded the protective diode.
It must not send a penetration electric current.
Condition:
Power level of 3.3V line ≧ Power level of 2.5V line ≧ Power level of 1.5V line
When the power level of 1.5V line is more than 0.4V, 3.3V line and 2.5V line must
reach the level of power more than 0.4V.
And when the power level of 2.5V line is more than 0.4V, 3.3V line must reach the
level of power more than 0.4V.
It is necessary to fall the power of 1.5V line before 3.3V line and 2.5V line are fallen, and to fall the power of 2.5V
line before 3.3V line is fallen.
It must not send a penetration electric current too.

3.3V (power range : 3.0 ∼3.6V)
2.5V (power range : 2.3∼ 2.7V)
1.5V (power range : 1.35∼ 1.65V)
It needs to rise less than 40ms from starting to rise the power of 2.5V.
(using power on reset of DRAM )
(reset release)
After all powers rising, it is necessary to keep resett ing more
than 0.5ms.
And it must not keep the reset conditions more than one minute.
After reset release, it is necessary to be more than 100ns for
IIC BUS control starting.
