10. Configuration Memory

The configuration memory consists of 2048 bits of EEPROM memory used for storage of passwords, keys, codes, and

also used for definition of security access rights for the user zones. Access rights to the configuration memory are

defined in the control logic and are not alterable by the user after completion of personalization.

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 zone as OTP (One-Time Programmable) memory. Fuses are designed for the

module manufacturer, card manufacturer and card issuer and should be blown in sequence, although all programming

of the device and blowing of the fuses may be performed at one final step.
