SPI Slave To AHB Bridge interface provides full support for the two-wire SPI synchronous serial interface, compatible with SPI version Block Guide 4.01 standard. Through its SPI compatibility, it provides a simple interface to a wide range of low-cost devices. SPI Slave To AHB Bridge IIP is proven in FPGA environment.The host interface of the SPI can be AMBA APB, AMBA AHB, AMBA AHB-Lite, AMBA AXI, AMBA AXI-Lite, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
SPI Slave To AHB Bridge IIP is supported natively in Verilog and VHDL
