97 / 105 page ST6215C/ST6225C 97/105 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. 0F9Bh T0 0F9Ch T1 0F9Dh T2 0F9Eh T3 0F9Fh Test ID 1 |
