Short Desc. : PE-SDMMCD -- SD 3.0 / eMMC 4.51 Device Controller
Overview :
The Posedge SD 3.0 / eMMC4.51 Device Controller (PE-SDMMCD300) is a highly configurable Device Controller compatible with SD Physical Layer Specification Version 3.0 and eMMC Specification Version 4.51.The PESDMMCD300 controller supports SPI, SD 1, 4 bit modes and eMMC 1, 4, 8bit modes. The Core is designed to operate at a maximum frequency of 208MHz for SD and 200MHz for eMMC. The simple and flexible interface of PESDMMCD300 controller enables the user to integrate effectively in any SOC system or with any system bus interface. The controller supports both Boot and Alternate Boot Mode Operation.

The SD 3.0 / eMMC4.51 Device Controller supports AHB Interface and works in DMA Mode of operation to transmit and receive data. The AHB Slave Interface provides the operational registers for Processor to configure the PE-SDMMCD300 controller. This controller also adds the flexibility to connect the Flash memory with all inputs as required.

The (PE-SDMMCD300) SD 3.0 / eMMC4.51 Device Controller Core is designed for low power, high performance, less gate count making it ideal for low-power and high-performance applications. The core was tested using rigorous verification methodology, consisting of directed tests, constrained random verification, and Error Injection cases.

The (PE-SDMMCD300) SD 3.0 / eMMC4.51 Device Controller Core has a very simple firmware interface. The core comes with an optimized software programming model, allowing any customer to meet their high system performance requirement while maintaining low CPU overhead. The architecture supports all security features such as Card Lock Password protection, Write Protection and also an optional Authentication based Content Protection. Cyclic Redundancy Code (CRC) Integrity checking is handled in Hardware. CRC7 is used for Command and CRC16 is for Data Integrity.
