TMS320C6748: The max clock for the MMC/SD card controller?

user5948244

Part Number: TMS320C6748

Hi,

I have another quesion about the MMC/SD card controller,because of the limit of SDIO spec 2.0 ,the max clock for the SDIO is 50M,

The MMC/SD card controller supports MMC (Multimedia Card) Specification v4.0，is the max clock also 50M or more?

Thanks.

Hi user5948244,

The maximum MMC Operating frequency (MMCSD_CLK) is 52 MHz at 1.2V and 1.3V.
You can find full details in TMS320C6748 datasheet Table 6-41at:
