SD Card 3.0 - eMMC 4.51 Device Controller

Arasan's eMMC 4.51 Device Controller IP provides a high-performance embedded flash storage solution for consumer, industrial, networking, automotive, and embedded systems. Fully compliant with the JEDEC JESD84-B45 eMMC 4.51 specification, the controller delivers bandwidth up to 1.6 Gbps while supporting advanced embedded storage capabilities such as command packing, dynamic device capacity management, extended partitioning, context IDs, and data tags. The controller is designed to simplify system integration through support for multiple boot modes, configurable data bus widths, DMA-based data transfers, and compatibility with a variety of NAND flash architectures. Security and reliability are enhanced through Replay Protected Memory Block (RPMB), sanitize and discard operations, write-protection mechanisms, password support, and CRC-based error detection. The architecture provides seamless integration into ASIC and FPGA designs through standard system interfaces and supports both legacy and next-generation eMMC storage devices. By abstracting flash management functions from the host processor, the controller reduces software complexity while delivering a scalable and standards-compliant storage subsystem solution
