描述 Description

The AT24C128SC/256SC provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 words of 8 bits each. The devices are optimized for use in smart card applications where low power and low-voltage operation may be essential. The devices are available in several standard ISO 7816 smart card modules (see Ordering Information). All devices are functionally equivalent to Atmel Serial EEPROM products offered in standard IC packages (PDIP, SOIC, TSSOP, dBGA), with the exception of the slave address and Write Protect functions which are not required for smart card applications.
