12.6 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
STMicroelectronics using the correctly filled OP-
TION LIST appended.
The STMicroelectronics Sales Organization will be
pleased to provide detailed information on con-
tractual points.
Listing Generation and Verification. When
STMicroelectronics receives the user’s ROM con-
tents, a computer listing is generated from it. This
listing refers exactly to the ROM contents and op-
tions 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
production of the specific customer MCU.
12.6.1 FASTROM Version
The ST62P15C/P25C are the Factory Advanced
Service Technique ROM (FASTROM) versions of
ST62T15C,T25C OTP devices.
They offer the same functionality as OTP devices,
but they do not have to be programmed by the
customer. The customer code must be sent to
STMicroelectronics in the same way as for ROM
devices. The FASTROM option list has the same
options as defined in the programmable option
byte of the OTP version. It also offers an identifier
option. If this option is enabled, each FASTROM
device is programmed with a unique 5-byte
number which is mapped at addresses 0F9Bh-
0F9Fh. The user must therefore leave these bytes
blanked.
The identification number is structured as follows:
with T0, T1, T2, T3 = time in seconds since 01/01/
1970 and Test ID = Tester Identifier.
