Designed to work with SD Memory, miniSD Memory, SD Combo, MMC, MMCplus, and
RS-MMC cards
Card bus clock frequency up to 52 MHz
Supports 1-/4-bit SD mode, 1-/4-/8-bit MMC modes
— Up to 200 Mbps data transfer for SD/MMC cards using four parallel data lines
— Up to 416 Mbps data transfer for MMC using 8 parallel data lines
Single- and multi-block read and write
Write-protection switch for write operations
Synchronous abort
Pause during the data transfer at a block gap
Auto CMD12 for multi-block transfer
Host can initiate non-data transfer commands while the data transfer is in progress
Fully configurable 128 32-bit FIFO for read/write data
Internal DMA capabilities
Supports booting from eSDHC. See
SD 1-bit
SD 4-bit
MMC 1-bit
MMC 4-bit
MMC 8-bit
Identification mode (up to 400 kHz)
MMC full-speed mode (up to 20 MHz)
MMC high-speed mode (up to 52 MHz)
SD full-speed mode (up to 25 MHz)
SD high-speed mode (up to 50 MHz)
SDHC_CLK is the internally generated clock signal that drives the MMC, or SD card.
SDHC_CMD I/O sends commands and receive responses from the card.
SDHC_DAT7–SDHC_DAT0 perform data transfers between the eSDHC and the card. If the
eSDHC is desired to support a 4-bit data transfer, SDHC_DAT7–SDHC_DAT4 can also be
optional and tied high.
