Description
LPDDR2 interface provides full support for the LPDDR2 interface, compatible with JESD209-2E and JESD209-2F specification and DFI-version 2.1 or higher specification Compliant. Through its LPDDR2 compatibility, it provides a simple interface to a wide range of low-cost devices. LPDDR2 Controller IP is proven in FPGA environment. The host interface of the LPDDR2 can be simple interface or can be AMBA AHB, AMBA AHB-Lite, AMBA APB, AMBA AXI, AMBA AXI-Lite, Tilelink, OCP, VCI, Avalon, PLB, Wishbone or Custom protocol.
