Multi-Port Memory Controller (MPMC)
ARM DDI 0287B Copyright © 2004, 2006 ARM Limited. All rights reserved. 10-3
• Power-saving modes dynamically control MPMCCKEOUT and
MPMCCLKOUT.
• Dynamic memory self-refresh mode supported by a Power Management Unit
(PMU) interface or by software.
• Controller supports 2K, 4K, and 8K row address synchronous memory parts. That
is, typical 512Mb, 256Mb, 128Mb, and 16Mb parts, with 8, 16, or 32 DQ (data)
bits per device.
• Two reset domains enable dynamic memory contents to be preserved over a soft
reset.
• A separate AHB interface for programming the MPMC registers. Enables the
MPMC registers to be situated in memory with other system peripheral registers.
• Locked AHB transactions supported.
• Support for all AHB burst types.
• Little and big-endian support.
• Support for the External Bus Interface (EBI) that enables the memory controller
pads to be shared.
• PrimeCell ID support.
Note
Synchronous static memory devices (burst mode devices) are not supported and DDR
SDRAM devices are not supported.
