Supply voltage specified in OCR register 2.7 3.6 V Except CMD0, 15,55,
ACMD41 commands
Supply voltage differentials (VSS1, VSS2) -0.3 0.3 V
Power up time 250 ms From 0v to VDD Min.
Note. The current consumption of any card during the power-up procedure must not exceed 10 mA.
• Bus Signal Line Load
The total capacitance CLthe 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:
Parameter Symbol Min. Max. Unit Remark
Bus signal line capacitance CL100 pF fPP ≤ 20 MHz, 7 cards
Single card capacitance CCARD 10 pF
Maximum signal line inductance 16 nH fPP ≤ 20 MHz
Pull-up resistance inside card (pin1) RDAT3 10 90 kΩMay be used for card
detection
Note that the total capacitance of CMD and DAT lines will be consist of CHOST, CBUS and one CCARD only since they are
connected separately to the SD Memory Card host.
Parameter Symbol Min. Max. Unit Remark
Pull-up resistance RCMD, RDAT 10 100 kΩTo prevent bus floating
Bus signal line capacitance CL250 pF fPP ≤ 5 MHz, 21 cards

• 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:
Parameter Symbol Min. Max. Unit Remark
Output HIGH voltage VOH 0.75*VDD V IOH = -100 μA @VDD min
Output LOW voltage VOL 0.125*VDD V IOL = -100 μA @VDD min
Input HIGH voltage VIH 0.625*VDD VDD + 0.3 V
Input LOW voltage VIL VSS – 0.3 0.25*VDD V
