SD3.0 Device Controller IP
Secure Digital eXtended Capacity (SDXC) specification was released in 2009 by the SD Association. SDXC memory cards can store between 32GB to 2TB of data and have a peak memory bandwidth of 104MB/s. These cards are geared to meet the performance, capacity, security and power requirements of consumer electronics products.
Arasan’s SD Memory Controller IP is easily adapted to interface with new NAND Flash technologies that can scale to meet the capacity and performance of SDXC. Arasan’s SDXC Memory Controller IP is compliant with the Physical Layer Specification Version 3.0 (SDXC). The controller supports Ultra-High Speed (UHS-l) mode with a peak bandwidth of 104MB/s.It can be used with multiple types of NAND Flash technology.
The SD3.0 Device Controller Core supports all of the standard SD security features such as write protection schemes, password protected card locking as well as authentication based content protection. The controller detects the insertion or removal of the card and ensures data is not altered when removed during read access.
The SDXC Memory Controller is designed to operate at a maximum frequency of 208 MHz. The interface supports SPI, SD 1-bit and 4-bit modes. The controller provides hardware support for all of the data protection schemes in the SDXC standard including password verification and management.
The SD3.0 Device controller handles block lengths or sector sizes of 512, 1024 and 2048 bytes. Cyclic redundancy code calculation is performed in hardware and is used to detect errors in the data stored in the memory. CRC 7 is used as the CRC for commands and CRC 16 bit is used for data.
