SDIO Device Controller IIP

SDIO DEVICE interface provides full support for the SDIO DEVICE synchronous serial interface, compatible with SD specification part E1 SDIO 4.10. Through its compatibility, it provides a simple interface to a wide range of low-cost devices. SDIO DEVICE IIP is proven in FPGA environment. The host interface of the SDIO can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.

SDIO Device Controller IIP IIP is supported natively in Verilog and VHDL
