Los Altos, Calif.Eureka Technology Inc. announced the immediate availability of SD/SDIO/MMC slave controller core that supports the Secure Digital (SD) and Multi-Media Card (MMC) formats.
The slave controller facilitates the design of SD memory, SDIO and MMC cards and reduces the development time of 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 the functions are provided by the core.
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 1-Kbyte to 32-Kbytes.
A hardware development board for SD/SDIO/MMC development will also be available soon.
