Power up time is defined as voltage rising time from 0 volt to VDD(min.) and depends on application parameters
such as the maximum number of SD Cards, the bus length and the characteristic of the power supply unit.
Supply ramp up time provides the time that the power is built up to the operating level (the host supply voltage)
and the time to wait until the SD card can accept the first command,
The host shall supply power to the card so that the voltage is reached to VDD(min.) within 250ms and start to
supply at least 74 SD clocks to the SD card with keeping CMD line to high. In case of SPI mode, CS shall be
held to high during 74 clock cycles.

After power up (including hot insertion, i.e. inserting a card when the bus is operating) the SD Card enters the
idle state. In case of SD host, CMD0 is not necessary. In case of SPI host, CMD0 shall be the first command to
send the card to SPI mode.
CMD8 is added in the Physical Layer Specification Version 2.00 to support multiple voltage ranges and used to
check whether the card supports supplied voltage. The version 3.00 host shall issue CMD8 and verify voltage
before card initialization. The host that does not support CMD8 shall supply high voltage range.
ACMD41 is a synchronization command used to negotiate the operation voltage range and to poll the cards
until they are out of their power-up sequence. In case the host system connects multiple cards, the host shall
check that all cards satisfy the supplied voltage. Otherwise, the host should select one of the cards and
initialize

The power ramp up time is defined from 0.5 V threshold level up to the operating supply voltage which is

When the host shuts down the power, the card V

avoid a situation that the operating current is drawn through the signal lines.
If the host needs to change the operating voltage, a power cycle is required. Power cycle means the power is
turned off and supplied again. Power cycle is also needed for accessing cards that are already in
To create a power cycle the host shall follow the power down description before power up the card (i.e. the card
