Part Status:
The 24LC01B (24XX01*) series of 1 Kbit Electrically Erasable PROM. 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 1.7 V 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.
