■ Timing chart

● Common

 Power-on timing

Be sure to input "L" to the RESETB pin before inputting the first command after power-on.

Be sure to enter "L" at the RESETB pin when the DVDD is below the (recommended) operating voltage range.

 Power-off timing

Shut down each power supply after changing to the power down status with PDWN commands.

DVDD

Status

Power-down

Shut down in the order of IOVDD, SPVDD, and DVDD or SPVDD, IOVDD, and DVDD.

It is possible that the IOVDD shuts down and then the SPVDD and DVDD shuts down at the same time,

or the SPVDD shuts down and then the IOVDD and DVDD shut down at the same time.

The DVDD, SPVDD and IOVDD can also shut down at the same time.

RESETB

After the power is turned on, the device enters the power-down state.

Start up in the order of DVDD, SPVDD and IOVDD or DVDD, IOVDD and SPVDD.

It is possible that the DVDD and SPVDD start up at the same time and then the IOVDD starts up, or the DVDD

and IOVDD starts up at the same time and then the SPVDD starts up.

The DVDD, SPVDD and IOVDD can also start up at the same time.

tRST is specified based on the last power-on pin.
