DDR3 SDRAM Controller

Overview

The Lattice Double Data Rate DDR3 Synchronous Dynamic Random Access Memory SDRAM Controller is a general-purpose memory controller that interfaces with industry standard DDR3 memory devices/modules compliant with JESD79-3, DDR3 SDRAM Standard, and provides a generic command interface to user applications. The DDR3 SDRAM is the next-generation DDR SDRAM memory technology which features faster speed, mitigated SSO, and reduced routing due to “fly-by” routing signals to SDRAM instead of low skew tree distribution. This core reduces the effort required to integrate the DDR3 memory controller with the remainder of the application and minimizes the need to directly deal with the DDR3 memory interface.

Support for all LatticeECP3 “EA” devices Interfaces to Industry Standard DDR3 SDRAM components and modules compliant with JESD79-3, DDR3 SDRAM Standard Interfaces to DDR3 SDRAM at speeds up to 400 MHz / 800 Mbps in -8 speed grade devices Supports memory data path widths of -8, -16, -24, -32, -40, -48, -56, -64 and -72 bits Supports x4, x8, and x16 device configurations Support for unbuffered DDR3 DIMM and DDR3 RDIMM module Supports up to one DIMM and two ranks per DIMM Programmable burst lengths of 8 fixed , chopped 4 or 8 on-the-fly , or chopped 4 fixed Programmable CAS latency

Programmable CAS Write Latency Read burst type of nibble sequential or interleave Supports automatic DDR3 SDRAM initialization and refresh Automatic Write Leveling for each DQS for DIMM applications. Option to switch of write leveling for On-board memory applications. Supports Power Down Mode Supports Dynamic On-Die Termination ODT controls Termination Data Strobe TDQS for x8 widths only LatticeECP3 I/O primitives manage read skews Read Leveling equivalent Automatic Programmable Interval Refresh or User Initiated Refresh Option for controlling memory reset outside the controller

The DDR3 SDRAM Controller is available as an IPexpress user configurable IP core, which allows the configuration of the IP and generation of a netlist and simulation file for use in designs. Please note that generating a bitstream may be prevented or the bitstream may have time logic present unless a license for the IP is purchased.
