The
PMCspan board allows users to customize their exact I/O requirements
with Motorola's VME based CPU modules designed around the PowerPlus
Architecture.
When
coupled with an MCG processor module, the PMCspan provides up to six
PMCs, more expansion capability than any other VMEbus processor
module. Each PMCspan supports either two single-wide or one
double-wide PCI Mezzanine Card (PMC). By stacking PMCspans, a total
of four additional single-wide PMCs can be added to MCG's compute
engines—either today or as future application growth demands.
The
PMCspan is a standard 6U single-slot VMEbus module that links to its
host board via a PCI expansion connector. It supports both front
panel and P2 I/O access for customer supplied PMCs.
