Definition of AT88SC101/102 Memory Partitions
FABRICATION ZONE (16 bits): Programmed by the manufacturer with a specific identifier for each customer. FUSE1 is blown by the manufacturer after programming the fabrication code, which makes the fabrication zone unalterable. ISSUER ZONE (64 bits): Programmed by the issuer before finalizing personalization. The data stored in the issuer zone is unalterable after FUSE2 is blown. SECURITY CODE (16 bits): Must be presented by the issuer to access circuit memory and personalize device before blowing FUSE2. This secures transportation between the manufacturer and the issuer. After the device is personalized and FUSE2 is blown, this code protects the access to the application zone(s) of the card. SECURITY CODE ATTEMPTS COUNTER (16 bits): Counts the number of incorrect security code attempts. The device is locked after 4 false presentations. USER PROTECTED ZONE (64 bits): Writing and erasing this zone is protected. The number of program/erase cycles is guaranteed up to 100,000. APPLICATION ZONE(S) (1024 or 512 bits): Reading and programming the application zone(s) are controlled by the first 2 bits of the zone (PR, RD) and by the security code (Tables 1 and 2). The erasure of each zone is protected by an erase key specific to each zone. APPLICATION ZONE ERASE KEY (32 or 48 bits): Must be presented to authorize the erasure of the application zone(s). The key(s) must be programmed during the personalization of the circuit. ERASE COUNTER (128 bits): Limits the number of erasures of the last zone to 128 or less. MEMORY TEST ZONE (16 bits): at this memory location. Allows pattern testing
