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 fabrication facility,  
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 config-  
ures 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 functions 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 reten-  
tion is guaranteed.
