RAM200 Memory Module
The RAM200 is the ECC DRAM memory mezzanine module that
(together with an LED mezzanine and an optional PCI mezzanine
card) plugs into the base board to make a complete MVME2603 or
MVME2604 single-board computer. See
Figure 1-18
.
RAM200 modules of 16, 32, 64, 128, or 256MB are available for
memory expansion. The ECC DRAM is controlled by the Falcon
memory controller chip set. The Falcon ASICs perform two-way
interleaving, with double-bit error detection and single-bit error
correction.
In addition to the ECC DRAM, the RAM200 module supplies 4MB
or 8MB of additional soldered-in 64-bit Flash memory. A jumper
header (J10) tells the Falcon chip set where in memory to fetch the
board reset vector. Depending on the configuration of J10, resets
execute either from Flash memory bank A or from bank B.
MVME712M Transition Module
The MVME712M transition module (
Figure 1-3
) and P2 adapter
board are used in conjunction with the following models of the
MVME2603/2604 base board:
MVME2603-2121A
MVME2604-2121A
MVME2603-2131A
MVME2604-2131A
MVME2603-2141A
MVME2604-2141A
MVME2603-2151A
MVME2604-2151A
MVME2603-2161A
MVME2604-2161A
The features of the MVME712M include:
❏
A parallel printer port (via P2 adapter)
❏
An Ethernet interface supporting AUI connections (via P2
adapter)
❏
Four EIA-232-D multiprotocol serial ports (via P2 adapter)
❏
An SCSI interface (via P2 adapter) for connection to both
internal and external devices
