Product Summary

The AT24C02 is a 2-Wire Bus Serial EEPROM which provides 2048 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 256 words of 8 bits each. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. The AT24C02 is available in space-saving 5-lead SOT23 package and is accessed via a 2-wire serial interface.
