• 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.

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 because they are
connected separately to the SD Memory Card host.
Host should consider total bus capacitance for each signal as the sum of CHOST, CBUS, and CCARD, these parameters are
defined by per signal. The host can determine CHOST and CBUS so that total bus capacitance is less than the card estimated
capacitance load (CL=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than
maximum value of CL(40 pF).

• 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 and JESD8-7, 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
