Application note
Table 5.
(values taken from
[1]
Compared to the SD-memory card, the MMC bus is limited to a maximum of only 30 pF
(SD-memory card is 40 pF maximum).
The eMMC contains pull-up resistors at the pins Data0 to Data7 to prevent floating of
unconnected data lines. All other MMCs do not contain any pull-up resistors to prevent
bus floating.
Two basic differences are the minimum resistor value of R
specified minimum of the SD-memory card specification, and the Data0 to Data7 pull-up
resistor values, starting at 50 kΩ instead of 10 kΩ in the SD-memory card specification
(see
Table 6.

Low-voltage levels are part of the dual voltage range card specification including also the high-voltage
range. The voltage range from 1.95 V to 2.7 V is undefined.
