The AT88SC1003 is a low-cost synchronous integrated circuit, designed for use in repaid and loyalty smart card applications. The AT88SC1003 provides 1024 bits of erial EEPROM (Electrically Erasable and Programmable Read Only Memory) within hree application zones, plus 64 bits in a code-protected zone. Security logic provides ccess protection through use of a 16-bit security code.
Additional EEPROM memory is available to hold unalterable information about the ard history. Separate zones are available for data written by the card manufacturer nd card issuer. After personalization of the memory by the issuer, an internal fuse is lown that secures critical memory areas of the device and configures the IC for use y the end customer. The action of blowing this fuse is irreversible. The AT88SC1003 s manufactured using low-power CMOS technology. EEPROM programming functions re accomplished using an internally generated high-voltage pump for single oltage supply operation. Program timing is controlled internally. Memory endurance s guaranteed to 100,000 erase/write cycles. Ten-year data retention is guaranteed.
