SDIO Device Controller IP

Description and Features

The SDIO Device Controller IP Core is full-featured, easy-to-use, synthesizable design that is easily integrated into any SoC or FPGA development. The SDIO Device Controller IP can be implemented in any technology. The SDIO Device Controller IP core supports the Part 1 Physical Layer Specification Version 3.01 and SD specification Part E1 SDIO version 3.00. It can also support a variety of host bus interfaces for easy adoption into any design architecture - AHB, APB, OCP, VCI, Avalon PLB, Wishbone or custom buses. The SDIO Device Controller IP is delivered in Verilog RTL that can be implemented in an ASIC or FPGA. The SDIO Device Controller IP is validated in using FPGA. The core includes RTL code, test scripts and a test environment for complete simulation.
