General Description

The MVME2300 is a VME processor module equipped with an MPC 603
or MPC604R microprocessor.
The product offers many standard features desirable in a computer
system—including Ethernet and debug ports, Boot ROM, flash memory,
DRAM, and interface for two PCI Mezzanine Cards (PMCs), contained in
a one-slot VME package. Its flexible mezzanine architecture allows
relatively easy upgrades of the I/O.
There are four standard buses on the MVME2300:
As shown in
from the Processor Bus to PCI. A W83C553 PCI/ISA Bridge (PIB)
Controller device performs the bridge function between PCI and ISA. The
Universe ASIC device provides the interface between the PCI Local Bus
and the VMEbus. A Falcon chipset is the ECC memory controller.
The Peripheral Component Interface (PCI) local bus is a key feature. In
addition to the on-board local bus peripherals, the PCI bus supports an
industry-standard mezzanine interface, IEEE P1386.1 PMC
(PCI Mezzanine Card).
