AT88SC1616C
The configuration zone consists of 2048 bits of EEPROM memory used for storing passwords,
keys, 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 personalization pro-
cess. 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.
