... In addition, both devices fully operate from 1.7V to 5.5V V The AT24CS01/02 provides the additional feature of a factory programmed, guaranteed unique 128-bit serial number, while maintaining all of the traditional features available in the 1-Kbit or 2-Kbit Serial EEPROM. The time consuming step of performing and ensuring true serialization of product on a manufacturing line can be removed from the production flow by employing the CS Series Serial EEPROM ...

... Upon a valid compare of the device address with hard-wired input pins A a compare is not successfully made, the chip will return to a standby state. Serial Number Access: The AT24CS01 and AT24CS02 utilizes a separate memory block containing a factory programmed 128-bit serial number. Access to this memory location is obtained by beginning the device address word with a ‘ ...
