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-
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.

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-
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.
