與Atmel AT24C系列接觸式芯片卡不兼容, 低成本

China production compatible with ATMEL AT24C series Contact chip Card, 是常見的未加密數據卡, 使用方法與EEPROM完全相同, 是突然掉電的電力數據存儲芯片, 即斷電記憶芯片. 存儲結構簡單,沒有分區, 只有兩個操作功能可以讀寫, 主要用於存儲一些要求不高的數據機密性. 寫入/擦除週期為 1,000,000 時; 100 多年的數據保留, 沒有動力的保存超過 40 年份.
This product has the advantage that the chip same quality, 低價.

AT24C128 SC/256SC provides 131,072/262,144 bits of serial electrically erasable and programmable read only memory (EEPROM) 組織為 16,384/32,768 的話 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.
