TS128M~2GSDM
Description
Transcend miniSD Card is non-volatile, which
means no external power is required to retain the
information stored on it. Besides, it is also a
solid-state device that without moving parts to skip or
break down. Transcend miniSD Card can offer an
incredible combination of fast data transfer, great
flexibility, excellent security and incredibly small size.

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:

Bus Signal Levels
miniSD Memory Card
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, the card input and output voltages shall be within the
following specified ranges for any V
