Card Module

Description

The AT24C1024SC provides 1,048,576 bits of serial electrically erasable and pro-

grammable read only memory (EEPROM) organized as 131,072 words of 8 bits each.

This device is optimized for use in smart card applications where low-power and low-

voltage operation may be essential. This device is available in a standard ISO 7816

smart card module (see Ordering Information, page 11). All devices are functionally

equivalent to Atmel serial EEPROM products offered in standard IC packages (PDIP,

SOIC, dBGA, LAP), with the exception of the slave address and write protect func-

tions, which are not required for smart card applications.
