Pci Mezzanine Interface; Pc87307 Isa Super I/O Device (Isasio) - Motorola MCP750 Installation And Use Manual

PCI Mezzanine Interface

A key feature of the MCP750 family is the Peripheral Component
Interconnect (PCI) bus. In addition to the on-board local bus devices
(Ethernet, graphics, etc.), the PCI bus supports an industry-standard
mezzanine interface, IEEE P1386.1 PCI Mezzanine Card (PMC).
PMC modules offer a variety of possibilities for I/O expansion through
Fiber Distributed Data Interface (FDDI), Asynchronous Transfer Mode
(ATM), graphics, and Ethernet ports. The base board supports PMC front
panel and rear transition module I/O.
The MCP750 supports one PMC slot. Four 64-pin connectors on the base
board (J11, J12, J13, and J14) interface with 32-bit or 64-bit IEEE P1386.1
PMC-compatible mezzanines to add any desirable function. The PCI
Mezzanine Card slot has the following characteristics:
Mezzanine Type
Mezzanine Size
PMC Connectors
Signaling Voltage
Refer to
the PMC connectors. For additional programming information, refer to the
PCI bus descriptions in the MCP750 Programmer's Reference Guide
(MCP750A/PG) and to the user documentation for the PMC modules that
you intend to use.
