MVME240x Module
The MVME240x module is a powerful, low-cost embedded VME
controller and intelligent PMC carrier board. The MVME240x is currently
available in the configurations shown in Table 1-1.
The MVME240x includes support circuitry such as ECC SDRAM,
PROM/Flash memory, and bridges to the Industry Standard Architecture
(ISA) bus and the VMEbus. The MVME240x’s PMC carrier architecture
allows flexible configuration options and easy upgrades. It is designed to
support one or two PMCs, plus one or two optional PCI expansion
mezzanine modules that each support up to two PMCs. It occupies a single
VMEmodule slot, except when optional PCI expansion mezzanine
modules are also used:
The MVME240x interfaces to the VMEbus via the P1 and P2 connectors,
which use the new 5-row 160-pin connectors as specified in the proposed
VME64 Extension Standard. It also draws +5V, +12V, and -12V power
from the VMEbus backplane through these two connectors. The +3.3V and
2.5V power, used for the PCI bridge chip and possibly for the PMC
mezzanine, is derived onboard from the +5V power.
