• 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 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.

	Pull-up resistance	RCMD	10	100	kΩ	To prevent bus floating

	Bus signal line capacitance	CL		40	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	kΩ	May 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
