T2M DDR5 Controller IP

DDR5 Controller IP

Description and Features

DDR5 is full-featured, easy-to-use, synthesizable design, compatible with DDR5 JESD79-5 and JESD79-5 Rev1.40 (Draft) specification and DFI-version 5.0 Compliant. Through its DDR5 compatibility, it provides a simple interface to a wide range of low-cost devices. DDR5 IP is proven in FPGA environment. The host interface of the DDR5 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.
