1
Support for two IEEE P1386.1 PCI mezzanine cards is provided via eight
64-pin SMT connectors. Front panel openings are provided on the
MVME240x board for the two PMC slots.
In addition, there are 64 pins of I/O from PMC slot 1 and 46 pins of I/O
from PMC slot 2 that are routed to P2. The two PMC slots may contain two
single-wide PMCs or one double-wide PMC. There are also two RJ45
connectors on the front panel: one for the Ethernet 10BaseT/100BaseTX
interface, and one for the async serial debug port. The front panel also
includes reset and abort switches and status LEDs.
PMCspan Expansion Mezzanine
An optional PCI expansion mezzanine module or PMC carrier board,
PMCspan, provides the capability of adding two additional PMCs. Two
PMCspans can be stacked on an MVME240x, providing four additional
PMC slots, for a total of six slots including the two onboard the
MVME240x. Table 1-2 lists the PMCspan models that are available for
use with the MVME240x.
PCI Mezzanine Cards (PMCs)
The PMC slots on the MVME240x board are IEEE P1386.1 compliant. P2
I/O-based PMCs that follow the PMC committee recommendation for PCI
I/O when using the 5-row VME64 extension connector will be pin-out
compatible with the MVME240x.
