Description	Two-wire Serial EEPROM
Datasheet	AT24HC02B_ATMELCorporation.pdf

The AT24HC02B 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 mercial applications where low-power and lowvoltage operation are essential.

The AT24HC02B is available in space-saving 8-lead PDIP, 8-lead JEDEC SOIC and 8-lead TSSOP packages and is accessed via a two-wire serial interface.
