ORDERING INFORMATION

The information required when ordering a custom

MCU is listed below. The ROM program may be

transmitted to SGS-THOMSON on EPROM(s) or an

EFDOS/MDOS* disk file.

To initiate a ROM pattern for the MCU, it is neces-

sary to first contact your local SGS-THOMSON re-

presentative or distributor.

EPROMs

One 2716 or 2732 type EPROMs, programmed with

the customer program (positive logic sense for ad-

XXX = Customer ID)

dress and data), may be submitted for pattern ge-

neration.

After the EPROM is marked, it should be placed in

conductive IC carriers and securely packed. Do not

use styrofoam.

VERIFICATION MEDIA

All original pattern media (EPROMs or floppy disk)

are filed for contractual purposes and are not retur-

ned. A computer listing of the ROM code will be ge-

nerated and returned along with a listing verification

form. The listing should be thoroughly checked and

the verification form completed, signed, and retur-

ned to SGS-THOMSON. The signed verification

form constitutes the contractual agreement for crea-

tion of the customer mask. If desired, SGS-THOM-

SON will program on blank EPROM from the data

file used to create the custom mask and aid in the

verification process.

ROM VERIFICATION UNITS (RVUs)

Ten MCUs containing the customer’s ROM pattern

will be sent for program verification. These units will

have been made using the custom mask but are for

the purpose of ROM verification only. For expedien-

cy they are usually unmarked, packaged in ceramic,

and tested only at room temperature and 5 volts.

These RVUs are included in the mask change and

are not production parts. The RVUs are thus not

guaranteed by SGS THOMSON. Quality Assu-

rance, and should be discarded after verification is

completed.

FLEXIBLE DISKS

The disk media submitted must be single-sided, EF-

DOS/MDOS* compatible floppies.

The customer must write the binary file name and

company name on the disk with a felt-tip-pen. The

minimum EFDOS/MDOS* system files, as well as

the absolute binary object file (Filename .LO type of

file) from the 6805 cross assembler, must be on the

disk. An object file made from a memory dump using

the ROLLOUT command is also acceptable. Consi-

der submitting a source listing as well as the follo-

wing files : filename .LX (DEVICE/EXORciser loada-

ble format) and filename .SA (ASCII Source Code).

These files will of course be kept confidential and are

used 1) to speed up the process in-house if any pro-

blems arise, and 2) to speed up the user-to-factory

interface if the user finds any software errors and

needs assistance quickly from SGS-THOMSON

factory representatives.

EFDOS is SGS-THOMSON Disk Operating System

available on development systems such as DE-

VICE...

MDOS* is MOTOROLA’s Disk Operating System

available on development systems such as EXOR-

ciser...

* Requires prior factory approval.

Whenever ordering a custom MCU is required, please contact your local SGS-THOMSON representative or

SGS-THOMSON distributor and/or complete and send the attached ”MCU customer ordering sheet” to your

local SGS-THOMSON Microelectronics representative.
