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.
