FM24C256E
The FM24C256E provides 262,144 bits of serial electrically erasable and programmable read-only memory (EEPROM) organized as 32,768 words of 8 bits each, with 128-bit UID and 64-byte Security Sector, and much improved the reliability by an internal ECC logic. The device's cascadable feature allows up to 8 devices to share a common 2-wire bus. The device is optimized for use in many industrial and commercial applications where low-power and low-voltage operations are essential.
