ST72521 DEVICE CONFIGURATION AND ORDERING INFORMATION (Cont’d)
14.2 DEVICE ORDERING INFORMATION AND TRANSFER OF CUSTOMER CODE
Customer code is made up of the ROM/FAS-
TROM contents and the list of the selected options
(if any). The ROM/FASTROM contents are to be
sent on diskette, or by electronic means, with the
S19 hexadecimal file generated by the develop-
ment tool. All unused bytes must be set to FFh.
The selected options are communicated to
STMicroelectronics using the correctly completed
OPTION LIST appended.
Refer to application note AN1635 for information
on the counter listing returned by ST after code
has been transferred.

14.2.1 Version-Specific Sales Conditions
To satisfy the different customer requirements and
to ensure that ST Standard Microcontrollers will
consistently meet or exceed the expectations of
each Market Segment, the Codification System for
Standard Microcontrollers clearly distinguishes
products intended for use in automotive environ-
ments, from products intended for use in non-auto-
motive environments.
It is the responsibility of the Customer to select the
appropriate product for his application.
