General Description; Mpc604 Processor - Motorola MVME2300SC Series Installation And Use Manual

General Description

The MVME2300SC is a VME processor module equipped with a
PowerPC
As described in the Features section, the MVME2300SC offers many
standard features desirable in a computer system — among them Ethernet
and debug ports, Boot ROM, Flash memory, DRAM, and an interface for
two PCI Mezzanine Cards (PMCs) — all 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 MVME2300SC:
In addition, the MVME2300SC supplies connectivity from both PMC
slots to an SCSA (Signal Computing System Architecture) backplane
TDM bus, if the system supports one, via shared pins on VME connector
P2.

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).

MPC604 Processor

The MVME2300SC is built with a PowerPC 604 processor chip. It can be
ordered with 32MB or 64MB of ECC DRAM, and up to 5MB of Flash
memory.
The PowerPC 604 is a 64-bit processor with 32 KB on-chip caches (32KB
data cache and 32KB instruction cache).
