1.3 ORDERING INFORMATION

The following section deals with the procedure for

transfer of customer codes to STMicroelectronics.

1.3.1 Transfer of Customer Code

Customer code is made up of the ROM contents

and the list of the selected mask options. The

ROM contents are to be sent on diskette, or by

electronic means, with the hexadecimal file gener-

ated by the development tool. All unused bytes

must be set to FFh.

The selected mask options are communicated to

STMicroelectronics using the correctly filled OP-

TION LIST appended. See page 76.

1.3.2 Listing Generation and Verification

When STMicroelectronics receives the user’s

ROM contents, a computer listing is generated

from it. This listing refers exactly to the mask which

will be used to produce the specified MCU. The

listing is then returned to the customer who must

thoroughly check, complete, sign and return it to

STMicroelectronics. The signed listing forms a

part of the contractual agreement for the creation

of the specific customer mask.

The STMicroelectronics Sales Organization will be

pleased to provide detailed information on con-

tractual points.
