T2M DDR LPDDR5 Controller IP

LPDDR5 Controller IP

Description and Features

LPDDR5 is full-featured, easy-to-use, synthesizable design, compatible with LPDDR5 JESD209-5, JESD209- 5A and JESD209-5B specification and DFI-version 5.0 specification Compliant. Through its LPDDR5 compatibility, it provides a simple interface to a wide range of low-cost devices. LPDDR5 Controller IP is proven in FPGA environment. The host interface of the LPDDR5 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.
