Note. The current consumption of any card during the power-up procedure must not exceed 10 mA.
• Bus Signal Line Load
The total capacitance CL the CLK line of the SD Memory Card bus is the sum of the bus master capacitance CHOST, the bus
capacitance CBUS itself and the capacitance CCARD of each card connected to this line:
CL = CHOST + CBUS + Ν*CCARD
Where N is the number of connected cards. Requiring the sum of the host and bus capacitances not to exceed 30 pF for
up to 10 cards, and 40 pF for up to 30 cards, the following values must not be exceeded:

• Bus Signal Levels
As the bus can be supplied with a variable supply voltage, all signal levels are related to the supply voltage.
To meet the requirements of the JEDEC specification JESD8-1A, the card input and output voltages shall be within the
following specified ranges for any VDD of the allowed voltage range:
