Secure digital input/output and MultiMediaCards Interface

(SDMMC)

The SD/SDIO, MultiMediaCard (MMC) host interface (SDMMC) provides an interface

between the AHB bus and SD memory cards, SDIO cards and MMC devices.

The SDMMC features include the following:

•

Full compliance with MultiMediaCard System Specification Version 4.51. Card support

for three different databus modes: 1-bit (default), 4-bit and 8-bit

•

Full compatibility with previous versions of MultiMediaCards (backward compatibility)

•

Full compliance with SD Memory Card Specifications Version 4.1. (SDR104

SDMMC_CK speed limited to maximum allowed IO 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 IO speed, SPI mode and UHS-II mode not supported)

•

Data transfer up to 104 Mbyte/s for the 8-bit mode (depending maximum allowed IO

speed)

•

Data and command output enable signals to control external bidirectional drivers.
