1 GENERAL DESCRIPTION

1.1 INTRODUCTION

The ST62P08C,P09C,P10C,P20C are the Factory

Advanced Service Technique ROM (FASTROM)

versions of ST62T08C,T09C,T10C,T20C OTP de-

vices.

They offer the same functionality as OTP devices,

selecting as FASTROM options the options de-

fined in the programmable option byte of the OTP

version.

1.2 ORDERING INFORMATION

The following section deals with the procedure for

transfer of customer codes to STMicroelectronics.

1.2.1 Transfer of Customer Code

Customer code is made up of the ROM contents

and the list of the selected FASTROM options.

The ROM contents are to be sent on diskette, or

by electronic means, with the hexadecimal file

generated by the development tool. All unused

bytes must be set to FFh.

The selected options are communicated to STMi-

croelectronics using the correctly filled OPTION

LIST appended.

1.2.2 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 ROM con-

tents and options which will be used to produce

the specified MCU. The listing is then returned to

the customer who must thoroughly check, com-

plete, sign and return it to STMicroelectronics. The

signed listing forms a part of the contractual agree-

ment for the production of the specific customer

MCU.

The STMicroelectronics Sales Organization will be

pleased to provide detailed information on con-

tractual points.
