24AA01-I/ST [Microchip]

The Microchip Technology Inc. 24AA01/24LC01B is a 1Kb Serial EEPROM. The device is organized as one block of 128 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 24XX01 also has a page write capability for up to 8 bytes of data. The 24XX01 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.
