LPDDR Controller IP

Description and Features

LPDDR is full-featured, easy-to-use, synthesizable design, compatible with JESD209A-1 and JESD209B specification and DFI-version 2.0 or higher specification Compliant. Through its LPDDR compatibility, it provides a simple interface to a wide range of low-cost devices. LPDDR Controller IP is proven in FPGA environment. The host interface of the LPDDR 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.
