Microprocessor Options
The MVME172P4 features the superscalar MC68060 micro-
processor which achieves superb integer and floating point
performance from its RISC hybrid architecture. The object
code compatibility of the MC68060 with earlier generations
allows a significant performance increase while preserving
software investment. For cost-sensitive applications where
floating point performance is not required, the optional
MC68LC060 can be ordered.
VMEbus Interface
VMEbus interface functionality is provided by the VMEchip2
ASIC designed by Motorola. In addition to controlling the sys-
tem’s VMEbus functions, the VMEchip2 includes a local bus
to/from VMEbus DMA controller, VME board support fea-
tures, as well as global control and status register (GCSR) for
interprocessor communications. The MVME172P4 also pro-
vides support for the VME D64 specification within the
VMEbus interface, further enhancing system performance.
Transition Module
An optional MVME712M transition module is available to
support the use of standard I/O connections for the
MVME172P4 series. This module takes the I/O connections
for the peripherals on board the MVME172P4 series from the
P2 connection of the module to a transition module that has
industry-standard connections.
IndustryPack Interface
A key feature of the MVME172P4 is the IndustryPack logic
interface. This interface provides a 32-bit data path for the
IndustryPack modules to the local MC68040 bus. Industry-
Pack modules provide a wide variety of connections to “real-
world” applications such as I/O, control, interface, analog and
digital functions. Up to four single-wide or two double-wide
IndustryPack modules can be installed on the MVME172P4
and still occupy only one VME slot. As I/O needs change, a
new IndustryPack module can be installed thus preserving
the customer’s overall investment.
Memory Expansion
The MVME172P4 is offered with a configurable SDRAM. The
size of the memory is determined by switch settings and the
memory devices.
Flexible Design
Because of the flexible nature of the MVME172P4 design,
some features can be removed from the board without affect-
ing hardware or software compatibility. Configurations are
available without SCSI or Ethernet. IndustryPack and VME
interfaces could also be removed. Contact you local Motorola
sales representative for more information.
