Introduction
This chapter provides a board-level hardware description of the
MVME162LX Embedded Controller. It contains a general overview of the
product along with a list of hardware features and a detailed functional
description. The controller's front panel switches and indicators are
included in the functional description. Additionally, a section on memory
maps is provided at the end of this chapter to familiarize you with the
controller's memory addresses and the corresponding devices accessed.
All of the controller's programmable registers that reside in ASICs are
covered in the MVME162LX Embedded Controller Programmer's
Reference Guide.
Overview
The MVME162LX Embedded Controller is based on the MC68040 or the
MC68LC040 microprocessor. The MC68040 microprocessor has a
floating-point (math) coprocessor and the MC68LC040 does not.
Various versions of the controller contain the following:
1Board Level Hardware
1 or 4 MB of parity-protected DRAM
4, 8, 16, or 32 MB of ECC-protected DRAM
128 KB of SRAM (with battery backup)
Time of day clock (with battery backup)
An optional LAN Ethernet transceiver interface
Four serial ports with an EIA-232-D interface
Six tick timers with watchdog timer(s)
Four EPROM sockets
1 MB flash memory (one flash device)
Two IndustryPack (IP) interfaces
An optional SCSI bus interface with DMA
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)
