AM5728: LVS SD card

Part Number: AM5728

Hi,

Can AM57x SD/MMC interface support LVS SD Card ? I'm not familiar with SD card specification. I know AM57x supports 1.8V I/O of SD card. Does it mean LVS SD card support ?

Thanks and regards,

Hideaki

Hi,

LVS concerns the voltage at which the card detection starts. LVS cards can start directly in 1.8V mode, without the need to switch card supply from 3.3V to 1.8V. However they are backward compatible and support voltage switching. See https://www.sdcard.org/developers/overview/low_voltage_signaling/index.html for details.
