Microcontroller interface with SD cards

Other Parts Discussed in Thread: MSP-EXP430FR5994

Does TI have any recommendations for a microcontroller that can interface with an SD card through SD mode and possibly support LVDS?

    Hello Jason,

    I'm not sure about the different modes, but we do have some MSP430 boards with SD card slots with example code you can use. Please see the MSP-EXP430F5529 or the MSP-EXP430FR5994 .

    Hi JH,

    Thanks for the response. I took a quick look at the schematic of both boards and it seems that they do not connect the DAT1 and DAT2 pin of the SD slot. I'm assuming that the microcontroller is communicating to it through SPI mode. I am looking for one that can communicate through SD mode (using all four data pins). Do you know if there is any microcontroller that can do this?

    Regards,
    Jason

    Jason,

    you are correct,t he MSP430s communicate to SD cards via SPI. After a quick chat with some colleagues, I do not think TI has an MCU with full SD card interface. Some of our bigger Processor parts may have it though, but that tells me its overkill for what you need.

    **CC32xx, one of our SimpleLink Wireless MCUs, has an SD card interface, but its only DATA0, so its effectively SPI***
