<strong>FTSDC010</strong><br />
SD MEMORY CARD HOST CONTROLLER<br />
Version 1.5 | January 2007<br />
Key Features<br />
General Description<br />
• AHB/66 MHz APB clock rate: 133 MHz<br />
• Compliant with the SD memory card<br />
protocol version 2.0<br />
• Supports the MMC bus protocol version 4.1<br />
• Supports the SDIO protocol version 1.10<br />
The <strong>FTSDC010</strong> is a Secure Digital (SD) host controller that functions as the<br />
master in an SD memory card, SDIO card, and MultiMediaCard card interface.<br />
It controls the communication between AHB and APB that is the hardware<br />
configuration and the SD bus. The core supports the SD memory bus<br />
protocol for the SD cards and the MMC bus protocol for the MMC cards.<br />
