PCI Mezzanine Interface
A key feature of the MCPN750A family is the PCI (Peripheral Component
Interconnect) bus. In addition to the on-board local bus devices (Ethernet,
etc.), the PCI bus supports an industry-standard mezzanine interface, IEEE
P1386.1 PMC (PCI Mezzanine Card). This support consists of two single-
wide or one double-wide PMC slots. Each slot provides four EIA-E700
AAAB connectors located on the MCPN750A board to interface to a
32/64-bit PMC to add any desirable function.
PMC modules offer a variety of possibilities for I/O expansion through
FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer
Mode), graphics, and Ethernet ports. The base board supports PMC front
panel and rear transition module I/O.
Two sets of four 64-pin connectors on the base board (J11 - J14 and J21 -
J24) interface with 32-bit or 64-bit IEEE P1386.1 PMC-compatible
mezzanines to add any desirable function. The PCI Mezzanine Card slots
have the following characteristics:
Refer to the Table on page 7-9 for the pin assignments of the PMC
connectors. For detailed programming information, refer to the PCI bus
descriptions in the MCPN750A CompactPCI Single Board Computer
Programmer’s Reference Guide (MCPN750A/PG) and to the user
documentation for the PMC modules you intend to use.
