The AT88SC1003 is a low-cost synchronous integrated circuit designed for use in prepaid and loyalty smart card applications. The AT88SC1003 provides 1024 bits of serial EEPROM (Electrically Erasable and Programmable Read Only Memory) within three application zones, plus 64 bits in a code-protected zone. Security logic provides access protection through use of a 16-bit security code. Additional EEPROM memory is available to hold unalterable information about the card history. Separate zones are available for data written by the fabrication facility, card manufacturer and card issuer. After personalization of the memory by the issuer, an internal fuse is blown that secures critical data.
The document describes the Atmel AT88SC1003, a low-cost synchronous integrated circuit manufactured using low-power CMOS technology. It is specifically designed for use in prepaid and loyalty smart card applications.
The device provides 1024 bits of serial EEPROM within three application zones, plus an additional 64-bit code-protected zone.
