Microchip | 24FC256-I/SN

The 24FC256 (24XX256*) series of 32 K x 8 (256 Kbit) Serial Electrically Erasable PROM, capable of operation across a broad voltage range (1.7 V to 5.5 V). 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 256 K 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.
