User Memory
The EEPROM user memory is divided into 16 user zones as shown in the memory map in
allow for different types of data or files to be stored in different zones. Access to the user zones is allowed only after
security requirements have been met. These security requirements are defined by the user in the configuration memory
during personalization of the device. The EEPROM memory page length is 16 bytes.
Table 1.
Configuration Memory
The configuration memory consists of 2048 bits of EEPROM memory used for storing system data, passwords, keys,
codes, and security-level definitions for each user zone. Access rights to the configuration zone are defined in the
control logic and may not be altered by the user. These access rights include the ability to program certain portions of
the configuration memory and then lock the data written through use of the security fuses.
Security Fuses
There are three fuses on the device that must be blown during the device personalization process. Each fuse locks
certain portions of the configuration memory as OTP memory. Fuses are designated for the module manufacturer, card
manufacturer and card issuer and must be blown in sequence.
