Chapter 13
IDE and Flash Media Interface
This chapter describes the operation of the bus interface to IDE and Flash Media, the interface setup,
timing and operation are provided as well as commonly used commands.
13.1
The MCF5253 memory bus allows connection of an IDE hard disk drive or SmartMedia flash card with a
minimum of external hardware.
illustrates an interface with both an IDE device and a SmartMedia device connected although both cannot
be supported simultaneously as the IDE_DIOR and IDE_DIOW signals can only be used to interface to
one or the other.

IDE and SmartMedia Overview
SmartMedia refers to Flash memory cards such as Compact Flash. For other
Flash Media such as Secure Digital (SD), MultiMedia Card (MMC) or
Memory Stick, refer to
For support as a Flash Media Interface, this solution is recommended.
This IDE and Flash Media Interface is not recommended for new IDE
designs. All new IDE designs should use the ATA Interface, refer to
Chapter 22, “USB, ATA DMA, and Clock Integration
drive IDE designs may still be supported through this legacy IDE Interface.
