  7. 4Revision History

2.5.4 SD/MMC

The SD/MMC connector on the AM574x IDK EVM is a MicroSD connector (part number SCHA5B0200). This is a standard SD/MMC card type of connector. It is connected to the MMC1 port of the AM574x processor that is optimized for this use. Refer to the AM574x Sitara Processors Silicon Revision 1.0 Data Manual (SPRS982) and the AM574x Technical Reference Manual (SPRUIH8) for supported card types and densities.

The SDWP input pin to the MMC1 port is connected to a 2-pin header, J44. The default state has the pin pulled high. Shorting the header pulls the pin low. The polarity of this input is programmable; thus, the hardware does not define whether a high or low level indicates Write Protest is active or not.

The transient protection implemented at the SDCARD connector is the TPD6E001.
