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:

Mezzanine Type	PMC (PCI Mezzanine Card)
	S1B: Single width, standard depth (74mm x 149mm)
Mezzanine Size	with front panel
	S2B: Double width, standard depth (149mm x
	149mm)
PMC Connectors	J11-J14 and J21-J24 (32/64-Bit PCI with front and
	64-bit rear I/O)
Signalling Voltage	Vio = 5.0Vdc

Refer to the Table on page 7-9for 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.
