• 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
