Motorola MVME2400 manual PMCspan Expansion Mezzanine, PCI Mezzanine Cards PMCs, PMCspan Models

MVME240x Description

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.

	Table 1-2. PMCspan Models
Expansion Module	Description
PMCSPAN-002	Primary PCI expansion mezzanine module. Allows two PMC modules
	for the MVME240x. Includes 32-bit PCI bridge.
PMCSPAN-010	Secondary PCI expansion mezzanine module. Allows two additional
	PMC modules for the MVME240x. Does not include
	32-bit PCI bridge; requires a PMCSPAN-002.

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.
