Ultra high-speed eMMC / SD host controller, enhanced to support eMMC

4.4 standard specification, for 832 MBps.

• Port 3 is specifically enhanced to support eMMC 4.4 specification, for

double data rate (832 Mbps, 8-bit port).

ESDHCV3 is backward compatible to ESDHCV2 and supports all the

features of ESDHCV2 as described below.

Enhanced multimedia card / secure digital host controller

• Ports 1, 2, and 4 are compatible with the “MMC System Specification”

version 4.3, full support and supporting 1, 4 or 8-bit data.

The generic features of the eSDHCv2 module, when serving as SD / MMC

host, include the following:

• Can be configured either as SD / MMC controller

• Supports eSD and eMMC standard, for SD/MMC embedded type cards

• Conforms to SD Host Controller Standard Specification, version 2.0, full

support.

• Compatible with the SD Memory Card Specification, version 1.1

• Compatible with the SDIO Card Specification, version 1.2

• Designed to work with SD memory, miniSD memory, SDIO, miniSDIO,

SD Combo, MMC and MMC RS cards

• Configurable to work in one of the following modes:

- SD/SDIO 1-bit, 4-bit

- MMC 1-bit, 4-bit, 8-bit

• Full/high speed mode.

• Host clock frequency variable between 32 kHz to 52 MHz

• Up to 200 Mbps data transfer for SD/SDIO cards using 4 parallel data

lines

• Up to 416 Mbps data transfer for MMC cards using 8 parallel data lines

The Ethernet media access controller (MAC) is designed to support both

10 Mbps and 100 Mbps Ethernet/IEEE Std 802.3™ networks. An external

transceiver interface and transceiver function are required to complete the

interface to the media.

The i.MX53xD also consists of HW assist for IEEE1588™ standard. See,

TSU and CE_RTC (IEEE1588) section for more details.

Fast infrared interface

The controller area network (CAN) protocol was primarily, but not

exclusively, designed to be used as a vehicle serial data bus. Meets the

following specific requirements of this application: real-time processing,

reliable operation in the EXTMC environment of a vehicle,

cost-effectiveness and required bandwidth. The FLEXCAN is a full

implementation of the CAN protocol specification, Version 2.0 B (ISO

11898), which supports both standard and extended message frames at

1 Mbps.
