TS4/8GUSDHC6-P3	4/8GB microSDHC Class 6 Card + Reader P3

Single card capacitance	CCARD		10	pF
Maximum signal line inductance			16	nH
Pull-up resistance inside card (pin1)	RDAT3	10	90	kΩ

fPP ≤ 20 MHz

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).
