SD/SDIO/MMC Slave Controller IP Core Enables High Performance SD and MMC Card Design

LOS ALTOS, California, November 1, 2007- Eureka Technology Inc., a leading intellectual property (IP) core provider, today announces the immediate availability of SD/SDIO/MMC slave controller core that supports Secure Digital (SD™) and Multi-Media Card (MMC™). Eureka has provided SD and MMC IP cores to many licensees since 2004. This latest addition of the slave controller completes the product line. A hardware development board for SD/SDIO/MMC development will also be available soon.

The slave controller facilitates the design of SD memory, SDIO and Multi-Media (MMC) cards and reduces the development time of any SD and MMC device projects. By using this IP core, customers no longer have to spend time on handling the SD or MMC bus protocol since such function is provided by the core. This allows our customers to focus primary on the added value of their products.

Ready to be integrated into an FPGA or ASIC, this controller handles the SD and MMC bus protocol on the card interface side and forward the request from the host to the user interface as simple memory read and write accesses. The core contains the standard SD and MMC register set and the core process register accesses locally, freeing the user logic from such house keeping tasks.

This IP core supports the latest SD and SDIO specification (version 2.0) and the latest MMC specification (version 4.2) for up to 8-bit data transfer. Many advanced features such as high capacity (SDHC), high speed mode, suspend and resume, SDIO and MMC Interrupt, SD Combo card, and multi-function card are supported. This slave controller core contains internal data buffer to improve data bandwidth and simplifies user logic design. The buffer size can vary from 1Kbytes to 32K bytes according to customerís need.
