VMEbus Interface

Another design advantage of the MVME167 is the use

of a second generation Application Specific Integrated

Circuit (ASIC). The ASIC interfaces the MVME167 to

the VMEbus for higher levels of quality, reliability, and

functionality.

In addition to controlling the system’s VMEbus

functions, the VMEbus Interface ASIC also includes a

local bus to/from VMEbus DMA controller, VME

board support features, as well as Global Control and

Status Register (GCSR) for microprocessor

communications. The MVME167 also provides

support for the VME D64 specification within the

VMEbus interface, further enhancing system

performance.

Transition Modules

Optional MVME712 Series transition modules are

available to support the use of standard I/O

connections for the MVME167 Series. These modules

take the I/O connections for the peripherals on-board

the MVME167 Series from the P2 connection of the

module to a transition module that has industry

standard connections.

Expansion Memory

Expansion memory is available for field upgrades.

Two types of expansion are possible. The first requires

replacing the existing memory mezzanine with a new

module. The second requires the addition of a second

mezzanine module, requiring a second VMEbus slot.

Development Software

Development software for the MVME167 series

includes the on-board debugger/monitor firmware and

driver packages. Object and source code is available

for application development. Firmware is included on

the board.

T h e M o t o r o l a C o m m i t m e n t

With the MVME167, Motorola continues its

commitment to meeting your needs with leading edge

technology. Adherence to industry standards and open

architecture provides the maximum in hardware and

software compatibility, while facilitating system

customization and expansion.

This commitment is evident in the MVME167.

Combining the high performance of the MC68040

microprocessor and integral floating-point unit with its

support of existing MC68000-based software, the

MVME167 single board computer offers the widest

range of flexibility, functionality, and performance

available for today’s systems integration and OEM

marketplace.
