A6/LC6B (XX6*) is a 6 Kbit Electrically Erasable PROM. The device is organized as eight blocks of 6 x 8-bit memory with a -wire serial interface. Low-voltage design permits operation down to.7v with standby and active currents of only μa and ma, respectively. The XX6 also has a page write capability for up to 6 bytes of data. The XX6 is available in the standard 8-pin PDIP, surface mount SOIC, TSSOP, x DFN and MSOP packages, and is also available in the -lead SOT- package.
