Bus Signal Line Load

The total capacitance C

the CLK line of the SD Memory Card bus is the sum of the bus master capacitance C

HOST

, the bus

capacitance C

BUS

itself and the capacitance C

CARD

of each card connected to this line:

Note that the total capacitance of CMD and DAT lines will be consist of C

and one C

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 C

HOST

, C

BUS

, and C

CARD

, these parameters are

defined by per signal. The host can determine C

HOST

and C

BUS

so that total bus capacitance is less than the card estimated

capacitance load (C

=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than

maximum value of C

(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 V

of the allowed voltage range:
