2Board Level Hardware

Description

This Chapter Covers 

❏ A general description of the MVME187 RISC Single Board 

Computer

❏ Features and specifications

❏ A board-level hardware overview

❏ A detailed hardware functional description, including front 

panel switches and indicators

❏ Memory maps

General Description

The MVME187 is a high functionality VMEbus RISC single board 

computer designed around the M88000 chip set. It features: 

❏ Onboard memory expansion mezzanine module with 

4, 8, 16, 32, 64 or 128MB of onboard DRAM

❏ SCSI bus interface with DMA

❏ Four serial ports with EIA-232-D interface

❏ Centronics (parallel) printer port

❏ Ethernet transceiver interface with DMA

❏ 187Bug debug monitor firmware

Onboard Memory Mezzanine Module

The MVME187 onboard DRAM mezzanine boards are available in 

different sizes and with programmable parity protection or Error 

Checking and Correction (ECC) protection. 

❏ The main board and a single mezzanine board together take 

one slot. 

❏ Motorola software supports mixed parity and ECC memory 

boards on the same main board. 

❏ Mezzanine board sizes are 4, 8, 16, or 32 MB (parity), or 4, 8, 

16, 32, 64, or 128 MB (ECC);

– Two mezzanine boards may be stacked to provide 256MB 

of onboard RAM (ECC) or 64 MB (parity). The stacked 

configuration requires two VMEbus slots. 

❏ The DRAM is four-way interleaved to efficiently support 

cache burst cycles.

❏ The parity mezzanines are only supported on 25 MHz main 

boards. 

A functional description of the Onboard DRAM starts on page 2-15.

SCSI Mass Storage Interface

The MVME187 provides for mass storage subsystems through the 

industry-standard SCSI bus. These subsystems may include 

❏ Hard and floppy disk drives

❏ Streaming tape drives

❏ Other mass storage devices.

A functional description of the SCSI Interface starts on page 2-22.

Serial Ports

The serial ports support standard baud rates of 110 to 38.4K baud. 

All four serial ports use EIA-232-D drivers and receivers located on 

the main board, and all the signal lines are routed to the I/O 

connector. 

A functional description of the Serial Port Interface starts on page 

2-18.

Parallel (Printer) Port

The 8-bit bidirectional parallel port may be used as a Centronicscompatible parallel printer port or as a general parallel I/O port.
