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.
Additional EEPROM memory is available to hold unalterable information about the
card history. Separate zones are available for data written by the card manufacturer
and card issuer. After personalization of the memory by the issuer, an internal fuse is
blown that secures critical memory areas of the device and configures the IC for use
by the end customer. The action of blowing this fuse is irreversible. The AT88SC1003
is manufactured using low-power CMOS technology. EEPROM programming func-
tions are accomplished using an internally generated high-voltage pump for single
voltage supply operation. Program timing is controlled internally. Memory endurance
is guaranteed to 100,000 erase/write cycles. Ten-year data retention is guaranteed.
