2.3

Power On/Off Sequence

Power on/off sequence and timing are shown in the figure and table below.

For power-up, 1.1-V and 1.8-V power (i.e. VDD, VCC18, and AVCC) must be supplied first, then 3.3-V power (i.e.

VCC33) must be supplied. The power-up sequence must be completed within 100 ms. Reset signal (i.e. RES#) must be held

to Low level during the power-up.

For Power-down, 3.3-V power (i.e. VCC33) must go down first and then 1.1-V and 1.8-V power (i.e. VDD, VCC18, and

AVCC). The power-down sequence must be completed within 100 ms.

Rise and fall time of each power supply for the power-up and the power-down must be larger than 10 µs.

Power supply voltages and reset signal must be applied with monotonic increase.

Do not apply a negative voltage to power supply voltages.

Stable clock must be supplied to EXTAL/XTAL or EXTCLKIN pin when reset signal (i.e. RES#) is driven high.
