Description The Atmel® AT24CS04 and AT24CS08 provides 4,096/8,192 bits of Serial Electrically Erasable and Programmable Read-only Memory (EEPROM) organized as 512/1,024 words of 8 bits each. The device is optimized for use in many industrial and mercial applications where low-power and low-voltage operation are essential. The AT24CS04/08 is available in space-saving, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN and 5-lead SOT23 packages and is accessed via a 2-wire serial interface. In addition, both devices fully operate from 1.7V to 5.5V VCC. The AT24CS04/08 provides the additional feature of a factory programmed, guaranteed unique 128-bit serial number, while maintaining all of the traditional features available in the 4-Kbit or 8-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. The...
