Atmel® AT88SC102 smart card 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 EEPROM within two Application Zones of 512 bits each, plus 64 bits in a Code Protected Zone, 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.

The AT88SC102 is manufactured using low-power CMOS technology and features its own internal high-voltage pump for single voltage supply operation. This smart card is guaranteed to 100,000 erase/write cycles and 100 year data retention and endurance up to one-million.

The AT88SC102 is supported by CardLogix  Smart Toolz™ development kit (SDK), Winplex™ API, and CardAppz™ application software. Each of these APIs also provides added security options for sensitive data.

The AT88SC102 is available in PVC, ABS, PET, Composite, and Polycarbonate ISO 7810, CR-80, SAM/SIM card, and Keychain form factors.
