The MM-6140D is a 32-bit/33MHz PMC (PCI
Mezzanine Card) memory buffer capable of burst
mode accesses at the full bandwidth of
32-bit/33MHz PCI, which translates to a rate of
up to 132 MB/sec. The MM-6140D can be placed
directly on any platform with a PMC connection.
It is commonly used as a high speed buffer for
fiber channels, DSPs, PowerPC, and Pentium SBCs.
In many PMC applications, the maximum speeds on
the memory read cycles can only be achieved by
using Push/Push technology. This is accomplished
with our on-board DMA initiator. Various drivers
are included so that the card can also be used
as a high speed RAMDisk.
The configurable space header of the MM-6140D
returns a class code of 05h, indicating that it
is a memory controller, and a sub-class code of
00h, indicating that it is a RAM module.
The MM-6140D is field upgradeable from 256MB
to 512MB, by installing a mezzanine card.
Reliability is ensured by burn-in and running
memory diagnostics that check operation for 48
hours while temperature-cycling boards from 0 to
70°C. Also, reliability is backed up by Micro
Memory, LLC's 1 Year Warranty. |
