AT88SC6416C
The configuration zone consists of 2048 bits of EEPROM memory used for storing pass-
words, keys and codes and defining security levels to be used for each user zone.
Access rights to the configuration zone are defined in the control logic and may not be
altered by the user.
Table 3. Configuration Zone
There are three fuses on the device that must be blown during the device personaliza-
tion process. Each fuse locks certain portions of the configuration zone as OTP
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.
