China production compatible with ATMEL AT24C series Contact chip Card, is a common unencrypted data card, use of the method and the EEPROM are exactly the same, is a sudden drop electric power data storage chip, namely the power lost memory chips. Storage structure is simple,no partitions, only two operating functions to read and write, mainly used to store some of the less demanding confidentiality of data. Write/erase cycles is 1,000,000 linako; 100 years of data retention, preservation without power for more than 40 lilemo.
This product has the advantage that the chip same quality, low price.

AT24C128 SC/256SC provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 16,384/32,768 mantsoe a 8 bits each. The devices are optimized for use in smart card applications where lowpower 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.
