General introduction of 24LC256-I/SM

General descriptions of 24LC256-I/SM

The    Microchip   Technology     Inc.  24AA256/24LC256/ 24FC256   (24XX256*)   is   a   32K   x   8   (256   Kbit)   Serial Electrically  Erasable    PROM,    capable    of  operation across   a   broad   voltage   range   (1.7V   to   5.5V).   It   has been developed for advanced, low-power applications such as personal communications or data acquisition. This device also has a page write capability of up to 64 bytes of data. This device is capable of both random and    sequential    reads   up  to  the  256K    boundary. Functional address lines allow up to eight devices on the   same   bus,   for   up   to   2 Mbit   address   space.   This device   is   available   in   the   standard   8-pin   plastic   DIP, SOIC, TSSOP, MSOP and DFN packages.
