AT88SC6416CRF
The EEPROM user memory is divided into 16 user zones as shown in the memory map in
5-1. Multiple zones 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 32 bytes.
Table 5-1.
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.
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 memory as OTP memory. Fuses are
designated for the module manufacturer, card manufacturer and card issuer and must be blown
in sequence.
