24LC04B/SN 
Datasheet
The Microchip Technology Inc. 24LC04B is a 4 Kbit Electrically Erasable PROM. The device is organized as two blocks of 256 x 8-bit memory with a 2-wire serial interface. Low-voltage design permits operation down to 2.5V, with standby and active currents of only 1 μA and 1 mA, respectively. The 24LC04B also has a page write capability for up to 16 bytes of data. The 24LC04B is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, 2x3 DFN and MSOP packages and is also available in the 5-lead SOT-23 package
