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 C
L
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
HOST
, C
BUS
and one C
CARD
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
L
=40 pF). The SD Memory Card guarantees its bus timing when total bus capacitance is less than
maximum value of C
L
(40 pF).

Bus Signal Levels
microSDHC Memory Card + Reader S3
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:
