Personalization

The 88RF PICC fuse bit functionality has been changed to allow enhanced security during the device personalization

process. See Appendix F and Appendix G for information.

Customers that do not program any of the security fuses until the end of the personalization process will not notice a

difference when personalizing 88RF PICCs. 88RF PICCs act the same as 88SC PICCs when the security fuses are in

the default state.

R.5.1. Write System Zone with Anti-Tearing

88RF PICCs do not support anti-tearing writes using the Write System Zone command. Attempts to activate this option

will result in a NACK response.

R.5.2. Reserved Memory

88RF PICCs do not allow writes to registers identified in the Configuration Memory Map as reserved. Any attempts to

write these registers will be NACKed. Attempts to read the Configuration Memory using a starting address which is a

reserved byte will be NACKed.

R.5.3. OTP Memory

88RF PICCs have 25 bytes of OTP memory available for customer use in the Configuration Memory; 88SC PICCs

have 27 bytes of OTP memory available for customer use. In 88RF PICCs bytes $0E and $0F are the read-only

Hardware Revision Register (HWR); in 88SC PICCs these bytes are available for customer use.
