Electrical Characteristics

4.10

Multi-Mode DDR Controller (MMDC)

The Multi-mode DDR Controller is a dedicated interface to DDR3/DDR3L/LPDDR2 SDRAM.

4.10.1

MMDC Compatibility with JEDEC-Compliant SDRAMs

The i.MX 6DualPlus/6QuadPlus MMDC supports the following memory types:

•

LPDDR2 SDRAM compliant to JESD209-2B LPDDR2 JEDEC standard release June, 2009

•

DDR3/DDR3L SDRAM compliant to JESD79-3D DDR3 JEDEC standard release April, 2008

MMDC operation with the standards stated above is contingent upon the board DDR design adherence to

the DDR design and layout requirements stated in the Hardware Development Guide for i.MX 6Quad,

6Dual, 6DualLite, 6Solo Families of Applications Processors (IMX6DQ6SDLHDG).

4.10.2

MMDC Supported DDR3/DDR3L/LPDDR2 Configurations

The table below shows the supported DDR3/DDR3L/LPDDR2 configurations:

General-Purpose Media Interface (GPMI) Timing

The i.MX 6DualPlus/6QuadPlus GPMI controller is a flexible interface NAND Flash controller with 8-bit

data width, up to 200 MB/s I/O speed and individual chip select. It supports Asynchronous timing mode,

Source Synchronous timing mode, and Samsung Toggle timing mode separately described in the following

subsections.

2 In this table:

• t means clock period from axi_clk frequency.

• CSA means register setting for WCSA when in write operations or RCSA when in read operations.

• CSN means register setting for WCSN when in write operations or RCSN when in read operations.

• ADVN means register setting for WADVN when in write operations or RADVN when in read operations.

• ADVA means register setting for WADVA when in write operations or RADVA when in read operations.
