Security Fuse Programming
Three security fuses are programmed at the end of the personalization process to lock the PICC configuration. The
Write Fuse Byte option of the Write System Zone command is used to program the fuses. A fourth fuse, SEC, is
already programmed by Atmel before CryptoRF leaves the factory. The fuses can only be programmed in the specified
order.
The security fuse programming sequence is as follows:
1.
2.
3.
The response to each Write System Zone command should be ACK, and the fuse byte contents will be returned in the
STATUS byte. After all three fuses are programmed, the device configuration is locked and personalization is
complete.
Secure Personalization
The 88RF PICCs support an optional encrypted personalization mode for programming the device secrets. The Secure
Personalization option is described in Appendix F. This option is not available on 88SC PICCs.
