Note:

The condition of A/D conversion characteristics is VREFHn = VCC18_ADCn (n = 0, 1). And power-up/down sequence should follow

VCC18_ADCn.

Note 1. Connect this USB power supply pin to VCC33 when the USB is not used. Do not leave this pin open.

Note 2. Connect Analog power supply pins to VCC18 when these analog functions are not used. Do not leave these pins open.

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.

Do not apply a voltage to any pins except P07_4 (USB_VBUSIN) until the power supply has powered up.

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