The AT88SC102 device is a low-cost, synchronous, secure memory integrated circuit, designed for use in prepaid and loyalty smart card applications. The AT88SC102 provides 1024 bits of serial Electrically Erasable and Programmable Read Only Memory (EEPROM) within two Application Zones, plus 64 bits in a code protected zone. Additional EEPROM memory and security logic provide security for smart card applications. Space is provided in the EEPROM memory for manufacturing records for both the smart card manufacturer and card issuer. After personalization, these records, and the state of the bit which enables the Erase Counter function, are locked and protected from modification for the lifetime of the product.
