The design guidelines in this document apply to PowerQUICCTM products that leverage the DDR IP core and are based on a compilation of internal platforms designed by Freescale. These guidelines minimize board-related issues across multiple memory topologies while allowing maximum flexibility for the board designer.
This document provides general hardware and layout considerations and guidelines for hardware engineers implementing a DDR4 memory subsystem. The rules and recommendations in this document serve as an initial baseline for board designers to begin their specific implementations, such as fly-by memory topology. NOTE.
DDR4 design checklist No. Task Completed Simulation 1 Ensure that optimal termination values, signal topology, and trace lengths are determined through simulation for each signal group in the memory implementation.

AM65x/DRA80xM DDR Board Design and Layout Guidelines 1 Overview The AM65x/DRA80xM processor supports three different types of DDR memories: DDR4, LPDDR4, and DDR3L. This allows customer board designs to be implemented with the memory type that best meets their target market at the lowest possible DDR SDRAM cost.
DDR4 SDRAMs are very prevalent in devices that use ASICs and FPGAs. In this tutorial we explore the basics of DDR4 memory starting with what it looks on the inside, how basic operations such as READ and WRITE work, DRAM page size, ranks and addressing.
This document provides general hardware and layout considerations and guidelines for hardware engineers implementing a DDR3 memory subsystem. The rules and recommendations in this document serve as an initial baseline for board designers to begin their specific implementations, such as fly-by memory topology. CAUTION.
