Enhanced Secure Digital Host Controller
20.1
The enhanced secure digital host controller (eSDHC) provides an interface between the host system and
these types of memory cards:
The eSDHC acts as a bridge, passing host bus transactions to SD/MMC cards by sending commands and
performing data accesses to or from the cards. It handles the SD/MMC protocol at the transmission level.

MultiMediaCard (MMC)
MMC is a universal low-cost data storage and communication medium designed to cover a wide
area of applications including mobile video and gaming, which are available from either pre-loaded
MMC cards or downloadable from cellular phones, WLAN, or other wireless networks. Old MMC
cards are based on a seven-pin serial bus with a single data pin, while the new high-speed MMC
communication is based on an advanced 11-pin serial bus designed to operate in a low voltage
range.
Secure digital (SD) card
The secure digital (SD) card is an evolution of old MMC technology. It is specifically designed to
meet the security, capacity, performance, and environment requirements inherent in the emerging
audio and video consumer electronic devices. The physical form factor, pin assignments, and data
transfer protocol are forward-compatible with the old MMC.
