Combination of superscalar microprocessor and
world-class quality VME products
The company that pioneered the VMEbus
single-board computer has added new dimensions in performance and
functionality. Motorola’s third-generation single-board computer,
the MVME177P, upholds the tradition by combining a superscalar
MC68060 microprocessor with the feature flexibility and world-class
quality found only in Motorola VME products.
The MVME177P’s compatibility with existing
M68000 family hardware and software allows users to realize RISC
performance levels while protecting their chassis, peripheral,
specialized I/O, and software investment. The MVME177P makes an
ideal solution for scientific, industrial, and high-end monitoring
and control applications.
The inclusion of the new “Petra”
application-specific integrated circuit (ASIC), which replaces
functions formerly implemented in the MCECC chip, improves the
performance of the memory subsystem. Memory configuration switches
enable the customer to tailor memory size for applications requiring
smaller memory configurations.

Notes:
- Flash/EPROM devices appear at
$FF800000–$FFBFFFFF and also appear at $0–$3FFFFF if ROM0 bit
in VMEchip2 EPROM control register is high (ROM0 = 1). ROM0 is
set to 1 after each reset. ROM0 bit must be cleared before
other resources (SDRAM or SRAM) can be mapped in this range
($0–$3FFFFF). On MVME177P, the Flash memory is mapped at
$0–$3FFFFF by hardware default through VMEchip2.
- This area is user-programmable. The
suggested use is shown in the table. The SDRAM decoder is
programmed in the Petra chip, and the local-to-VMEbus and
local-to-VSB decoders are programmed in the VMEchip2.
- Size is approximate.
- Cache inhibit depends on devices in
area mapped.
- This area is not decoded. If these
locations are accessed and the local bus timer is enabled, the
cycle times out and is terminated by a TEA signal.

VMEbus Interface
Another design advantage of the MVME177P is the use
of a second-generation application-specific integrated circuit (ASIC).
The ASIC interfaces the MVME177P 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 MVME177P 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 MVME177P
series. This module takes the I/O connections for the peripherals
on-board the MVME177P series from the P2 connection of the module to
a transition module that has industry-standard connections.
Development Software
Development software for the MVME177P series
includes the on-board debugger/monitor firmware. Object and source
code is available for application development. Firmware is included
on the board.
