eSPI LPC Bridge IIP

eSPI LPC Bridge interface is full-featured, easy-to-use, synthesizable design, compatible with Standard LPC Interface specification. Through its LPC compatibility, it provides a simple interface to a wide range of low-cost devices. eSPI LPC Bridge IIP is proven in FPGA environment.The host interface of the eSPI LPC Bridge can be simple interface or can be AMBA APB, AMBA AHB, AMBA AXI, VCI, OCP, Avalon, PLB, Tilelink, Wishbone or Custom protocol.

eSPI LPC Bridge IIP IIP is supported natively in Verilog and VHDL
