24AA02H,24LC02BH DataSheet
http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gif24AA02H/24LC02BH 2K I2C? Serial EEPROM with Half-Array Write-ProtectThe Microchip Technology Inc. 24AA02H/24LC02BH (24XX02H*) is a 2 Kbit Electrically Erasable PROM. The device is organized as one block of 256 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 1.7V, with standby and active currents of only 1 μA and 1 mA, respectively. The 24XX02H also has a page write capability for up to 8 bytes of data. The 24XX02H is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 TDFN and MSOP packages, and is also available in the 5-lead SOT-23 and SC-70 packages.
