Secure digital input/output and MultiMediaCards interface
(SDMMC)
The SDMMC (SD/SDIO embedded MultiMediaCard e•MMC™ host interface) provides
an interface between the AHB bus and SD memory cards, SDIO cards and e•MMC devices.
The MultiMediaCard system specifications are available through the MultiMediaCard
association website at www.mmca.org, published by the MMCA technical committee.
SD memory card and SD I/O card system specifications are available through the SD card
Association website at www.sdcard.org.
The SDMMC features include the following:
•
Compliance with Embedded MultiMediaCard System Specification Version 5.1
Card support for three different databus modes: 1-bit (default), 4-bit and 8-bit
(HS200 SDMMC_CK speed limited to maximum allowed I/O speed) (HS400 is not
supported).
•
Full compatibility with previous versions of MultiMediaCards (backward compatibility).
•
Full compliance with SD memory card specifications version 6.0
(SDR104 SDMMC_CK speed limited to maximum allowed I/O speed, SPI mode and
UHS-II mode not supported).
•
Full compliance with SDIO card specification version 4.0
Card support for two different databus modes: 1-bit (default) and 4-bit
(SDR104 SDMMC_CK speed limited to maximum allowed I/O speed, SPI mode and
UHS-II mode not supported).
