• Power Supply Voltage

Parameter Symbol Min. Max. Unit Remark

Supply voltage VDD 2.7 3.6 V

Output High Voltage VOH 0.75* VDD V IOH=-100uA@VDD Min.

Output Low Voltage VOL 0.125* VDD V IOL=100uA@VDD Min.

Power up time 250 ms From 0v to VDD Min.

• Current Consumption

The current consumption is measured by averaging over 1 second.

‧Before first command: Maximum 15 mA

‧During initialization: Maximum 100 mA

‧Operation in Default Mode: Maximum 100 mA

‧Operation in High Speed Mode: Maximum 200 mA

‧Operation with other functions: Maximum 500 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.

Parameter Symbol Min. Max. Unit Remark

Pull-up resistance RCMD

RDAT

10 100 kΩTo prevent bus floating

Bus signal line capacitance CL40 pF 1 card

CHOST+CBUS shall not exceed

30 pF

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:

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
