MIPI RFFE SPI I2C Slave interface provides full support for the two-wire MIPI RFFE synchronous serial interface with SPI and I2C overlay, compatible with RFFE, SPI and I2C specification. Through its RFFE compatibility, it provides a simple interface to a wide range of low-cost devices. MIPI RFFE SPI I2C Slave IIP is proven in multiple ASIC.The host interface of the MIPI RFFE/SPI/12C can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.
