13.56 MHz CryptoRF® EEPROM Memory 32 Kbits

Atmel Corporation 

4. User Memory

The EEPROM user memory is divided into 16 user zones as shown in the memory map in Table

4-1. 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.

5. 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.

5.1 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.
