Sanddisk SD Card Voltage

Guest
Hi,
am very new to electronics and have little knowledge, am really
software engineer, Im trying to hook up a SD card to a
microcontroller, the specification for sanddisk SD Cards states that a
operational voltage of 3.1 to 3.5 voltage is requires, now my board
will (other components) will be using 3.0 volts, would a 0.1 under
voltage pose a problem, do I require another power source for the sd
card? Any input would be appreciated.

Thanks for your time

Richard.
 
..1 VDC should not jeporadize the functions, surprised you are not using
nominal 3.3 VDC.
