Note. The current consumption of any card during the power-up procedure must not exceed 10 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. Requiring the sum of the host and bus capacitances not to exceed 30 pF for up to 10 cards, and 40 pF for up to 30 cards, the following values must not be exceeded: Parameter Bus signal line capacitance Single card capacitance Maximum signal line inductance Pull-up resistance inside card (pin1) Symbol CL CCARD RDAT3 Min.
