    Reduce power consumption in the SD card.

    I am using micro SD card to log data from sensor. It logs data every 15 minutes and then goes to sleep. I am using MSP430G2553 uc from TI. I am using 1000 mAh battery, still battery is not lasting for a week. While the uc sleeps, micro SD card continuously consumes power. Is is possible to reduce power consumption drastically, without changing schematic. Schematic and code is attached below.

    Regards,
    Tapas

    Take a look at Switching off SD cards for Low Power Data Logging for inspiration.
