The MVME172P4 allows VME embedded controller users to achieve the
price-performance value of RISC architectures while maintaining MC68000
object code compatibilit y. By combining the MC68060 superscalar perfor­mance with a wide rang e of optional features an d th e In dus try P ac k in terf ace ,
OEMs can select the exact prod uct for thei r applic ation rather th an payi ng for
unwanted features.

The inclusion of the n ew “Petra” ap plicat ion-spec ific i ntegrate d circuit (ASIC),
which replaces functions formerly implemented in the IP2 chip, MC2 chip,
and MCECC chip, improves the performance of the memory subsystem.
Memory configur ation swit ches e nable th e cust om er to tailo r me mory s ize for
applications requiring smaller memory configurations.

Microprocessor Options

The MVME172P4 features the superscalar MC68060 micro­processor which achiev es superb integer and fl oating point
performance from its RI SC 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 fea­tures, as well as globa l control a nd status r egister (G CSR) for
interprocessor communications. The MVME172P4 also pro­vides 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 b oard the MVME17 2P4 se ries fro m 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. Industry­Pack modules provide a wide variety of connections to “real­world” applications suc h 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 off ered with a co nfigurable 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 affect­ing hardware or software compatibility. Configur ations are
available without SCSI or Ethernet. IndustryPack and VME
interfaces could al so be removed. Contact yo u local Mo torola
sales representative for more information.
