LPDDR4 is full-featured, easy-to-use, synthesizable design, compatible with LPDDR4 JESD209-4, JESD209-4A, JESD209-4B, JESD209-4C, JESD209-4X and JESD209-4Y (Proposed) specification and DFI-version 4.0 or 5.0 specification Compliant. Through its LPDDR4 compatibility, it provides a simple interface to a wide range of low-cost devices. LPDDR4 IIP is proven in FPGA environment.The host interface of the LPDDR4 can be simpleinterface or can be AMBA AHB, AMBA AHB-Lite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
LPDDR4 Controller IIP is supported natively in Verilog and VHDL
