component side of the board.

2. Avoid placing boards with high power dissipation adjacent to the

MVME162.

3. Use low-power IP modules only.  The preferred locations for IP modules

are position a (J2 and J3) and position d (J18 and J19).

FCC Compliance

The MVME162 was tested without IndustryPacks in an FCC-compliant chassis

and meets the requirements for Class A equipment.  FCC compliance was

achieved under the following conditions:

1. Shielded cables on all external I/O ports.

2. Cable shields connected to earth ground via metal shell connectors

bonded to a conductive module front panel.

3. Conductive chassis rails connected to earth ground.  This provides the

path for connecting shields to earth ground.

4. Front panel screws properly tightened.

For minimum RF emissions, it is essential that the conditions above be

implemented. Failure to do so could compromise the FCC compliance of the

equipment containing the module

General Description

The MVME162 is a double-high VMEmodule equipped with an MC68LC040

or optional MC68040 microprocessor.  (The MC68040 microprocessor has a

floating-point coprocessor; the MC68LC040 does not.)

The MVME162 has 1MB, 4MB, or 8MB of parity-protected DRAM; 512KB

SRAM (with battery backup); a TOD clock (with battery backup); an optional

LAN Ethernet transceiver interface with DMA, two serial ports (EIA-232-D

and EIA-232-D/EIA-530); six tick timers with watchdog timer(s); optional

SCSI bus interface with DMA; 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

Input/Output (I/O) signals are routed through backplane connector P2.  A P2

adapter board or LCP2 adapter board routes the signals and grounds from

connector P2 to an MVME712 series transition module (MVME712-12.

MVME712-13. MVME712A, MVME712AM, or MVME712M).  The transition

module routes the signals to the appropriate configuration headers and

industry-standard connectors.  Refer to the MVME712-12. MVME712-13.

VMEbus Interface

The optional VMEchip2 ASIC is the VMEbus interface for the MVME162.

(This option is a factory build and cannot be added in the field.)  VMEchip2

features include:

Two programmable 32-bit tick timers

A programmable watchdog timer

Programmable map decoders for the master and slave interfaces

A VMEbus to/from local bus DMA controller

A VMEbus to/from local bus non-DMA programmed access interface

A VMEbus interrupter

A VMEbus system controller

A VMEbus interrupt handler

A VMEbus requester

Processor-to-VMEbus transfers can be D8. D16. or D32.  VMEchip2 DMA

transfers to the VMEbus, however, can be D16. D32. D16/BLT, D32/BLT, or

D64/MBLT.

No-VMEbus-Interface Option

If desired, the MVME162 can function as an embedded controller without a

VMEbus interface (i.e., without the optional VMEchip2). Contact your local

Motorola sales office for ordering information.

MCchip

The Memory Controller (MCchip) ASIC provides four 32-bit programmable

tick timers and an interface to the LAN chip, SCSI chip, serial port chip,

BBRAM, PROM/Flash, SRAM, DRAM, reset control, watchdog timers, access

timers, and interrupter logic.

Flash Memory and EPROM

The MVME162 is equipped with 1MB of Flash memory and an EPROM socket

ready for the installation of the EPROM, which may be ordered separately.

Flash memory is either a single device organized in a 1Mbit x 8 configuration

or four devices organized in a 256Kbit x 8 configuration.  The EPROM location

is a standard JEDEC 32-pin PLCC capable of four Mbit densities (128 Kbit x 8;

256 Kbit x 8; 512 Kbit x 8; 1 Mbit x 8) organized as a 512Kbit x 8 device.  A

jumper allows reset code to be fetched either from Flash memory or from the

EPROM.

IndustryPack Modules

Up to four IndustryPack (IP) modules may be installed on the MVME162.  The

interface between the IPs and MVME162 is the IndustryPack Interface

Controller (IPIC) ASIC.  Access to the IPs is provided by four 3M connectors

located behind the MVME162 front panel.

Optional SCSI Interface

An NCR 53C710 coprocessor provides the SCSI interface for the MVME162.

Optional LAN Ethernet Transceiver Interface

An Intel 82596CA controller provides the LAN Ethernet transceiver interface

for the MVME162.

Required Equipment

The following equipment is required to complete an MVME162 system:

System console terminal

Disk drives and controllers

Operating system

MVME712 series transition module (MVME712-12. MVME712-13.

MVME712A, MVME712AM, MVME712B, or MVME712M); P2 Adapter

Board or LCP2 Adapter Board; and cable

MVME162Bug Firmware

The 162Bug package, MVME162BUG, is a powerful evaluation and debugging

tool for systems built around the MVME162 CISC-based microcomputers.

Facilities are available for loading and executing user programs under

complete operator control for system evaluation.  162Bug includes commands

for display and modification of memory, breakpoint and tracing capabilities,

a powerful assembler/disassembler useful for patching programs, and a self
