ORDERING INFORMATION

To ensure compatibility between the EPROM/OTP

parts and the corresponding ROM families, the fol-

lowing information is provided. the user should

take this information into account when program-

ming the memory and OSD characters of the

EPROM parts.

Communication of the ROM Codes. To commu-

nicate the contents of memories to SGS-THOM-

SON, the customer has to send:

– one file in INTEL INTELLEC 8/MDS FOR-

MAT (either as an EPROM or in a MS-DOS 5”

diskette) for the ODD and EVEN OSD Character

OSD ROM/EEPROM

– one file in INTEL INTELLEC 8/MDS FOR-

MAT (either as an EPROM or in a MS-DOS 5”

diskette) for the EEPROM initial content (this

file is optional)

– a filled Option List form as described in the

OPTION LIST paragraph.

The ROM code must be generated with ST6 as-

sembler. Before programming the EPROM, the

buffer of the EPROM programmer must be filled

with FFh.

For shipment to SGS-THOMSON the EPROMs

should be placed in a conductive IC carrier and

packaging carefully.

Customer EEPROM Initial Contents:

Format

a. The content should be written into an INTEL IN-

TELLEC format file.

b. Undefined or don’t care bytes should have the

content FFh.

OSD Test Character. IN ORDER TO ALLOWTHE

TESTING OF THE ON-CHIP OSD MACROCELL

THE FOLLOWING CHARACTER MUST BE PRO-

VIDED AT THE FIXED 3Fh (63) POSITION OF

THE SECOND OSD BANK.

Listing Generation & Verification. When SGS-

THOMSON receives the files, a computer listing is

generated from them. This listing refers extractly to

the mask that will be used to produce the micro-

controller. Then the listing is returned to the cus-

tomer that must thoroughly check, complete, sign

and return it to SGS-THOMSON. The signed list

constitutes a part of the contractual agreement for

the creation of the customer mask. SGS-THOM-

SON sales organization will provide detailed infor-

mation on contractual points.
