Description

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.
