Appendix D. Configuration Memory Maps
The Configuration Memory contains all of the system information used to configure the User Zones, plus 27 bytes of
OTP memory that the customer can use to store data of any kind. The data in the Configuration Memory is locked by
programming fuses during the personalization process so that the PICC configuration cannot be changed by the end
user.

Access rights to the Configuration Memory are fixed in logic and are controlled by the security fuses. Refer to
Appendix G for access control and fuse information. The Read System Zone and Write System Zone commands are
used to access the Configuration Memory.
The contents of the Configuration Memory registers affect the functionality of CryptoRF and should be changed from
their default configuration only after careful consideration. Incorrect or invalid settings can disable the device or prevent
it from communicating with the PCD.
Configuration Memory registers marked as “Reserved” or RFU must not be changed and cannot be used for customer
data. Only 27 bytes of OTP memory are available for general customer use on 88SC PICCs and 25 bytes of OTP
memory are available on 88RF PICCs, all other registers have assigned functionality. The OTP memory bytes available
for customer use are described in Appendix E.
