Introduction
This chapter describes the board level hardware features of the
700/800-series MVME162LX VME Embedded Controller. The
chapter is organized with a board level overview and features list
in this introduction, followed by a more detailed hardware
functional description. Front panel switches and indicators are
included in the detailed hardware functional description. The
chapter closes with some general memory maps.
All MVME162LX programmable registers that reside in ASICs are
covered in the
MVME162LX Embedded Controller ProgrammerÕs
Reference Guide.
Overview
The MVME162LX is based on the MC68040 microprocessor.
Various versions of the MVME162LX have parity-protected DRAM
(4MB, 8M, or 16MB); or ECC-protected DRAM (4MB, 8MB, 16MB,
or 32MB); 128KB of SRAM (with battery backup); a time-of-day
clock (with battery backup); an optional LAN Ethernet transceiver
interface; four serial ports with EIA-232-D interface; six tick timers
with watchdog timer(s); two EPROM sockets; 2MB Flash memory
(one Flash device); two IndustryPack (IP) interfaces with DMA;
optional SCSI bus interface with DMA; and an optional VMEbus
interface (local bus to VMEbus/VMEbus to local bus, with
A16/A24/A32, D8/D16/D32 bus widths and a VMEbus system
controller).
Input/Output (I/O) signals are routed through industry-standard
connectors on the MVME162LX front panel; no adapter boards or
transition modules are required. I/O connections include an
optional 68-pin SCSI connector, an optional DB-15 Ethernet
